20 Days of Prototypes Update – Under the Radar Games

20 days of prototypes is progressing smoothly! I’m 9 days in so far and have made 5 different bite sized game prototypes with the new dev tools. Aiming for 10 prototypes by the end and then the idea is to pick the most promising one and develop it into the next BrainGoodGame!

You can follow along on the discord and Twitter. (Links in the sidebar)

Also thanks for the shoutout by Under the Radar games about Solar Settlers on mobile. Happy to see this game continue to get noticed long after release! You can find the article below.

Stay tuned for an article on Action Funnels as briefly described in the Playfulness article.

Happy Valentine’s Day,


Under The Radar Games That You Should Play!

Skill Compensation

Something I’ve been meaning to blog about for a long time is a concept I personally think of as Skill Compensation (I briefly touched on it here). Some alternative names for this game property might be Feedback Accuracy or Performance Compensation. Let’s take a shot at a definition:

Skill Compensation is the degree to which a player’s performance is reflected in the final outcome of a match. Phrased another way, it is the extent to which “the better player wins”*. 

The skills measured in a game like basketball might include running, passing, shooting accuracy, passing accuracy and decision making ability. In a game like “War” there are no skills measured whatsoever. Therefore War has no Skill Compensation.

In a match of a game that is primarily a strategy or decision making game, a player’s skill is primarily a function of how valuable their decisions are in terms of maximizing their win probability/expected value (“EV”).

Interestingly, in a game like Yomi, for any given game state/turn of the game, there exists a single “best” play in terms of raw EV. However, because the system has both you and your opponent act simultaneously, it is possible to “win” a hand by doing the “wrong” play. Frank Lantz talks about this concept in his article on Donkeyspace. This means that a given turn of Yomi has less than perfect Skill Compensation, if we set aside any value from the skill “reading” or “predicting” the opponent.

Simultaneous action in Yomi. Notably, Yomi still features a lot of depth/strategic consideration possible beyond “reading” or “predicting”.

However, crucially, despite the fact that simultaneous actions tend to lower Skill Compensation, the depth of the game has not necessarily decreased; there may still be the same about of strategic consideration, calculation and skill possible. Even though you might be rewarded for making the wrong move and punished for making the right one, the “right” or “more correct” move or set of moves still exist for players to find. This is also the case for games that feature a significant degree of output randomness, like Hearthstone or Risk. While a given game may feature more or less of either, Depth and Skill Compensation are not the same thing.

Pictured: lowered Skill Compensation.
Cards like this lower Skill Compensation but may actually increase depth, because players may have to contend with more possible future game states.

There are also advantages to adding a system like simultaneous actions to a system. It allows for weaker players to have intermediate successes even when playing the “wrong” move. It tends to allow for the hope of comebacks. And it allows us to tell stories about how we “just knew” the opponent would do that, which can be fun and exciting. Similarly output randomness, or any number of Skill Compensation reducing mechanisms can fuzz up the feedback and also allow for weaker players or players who have fallen behind to have hope. It can allow for a wider range of “valid” or “justifiable” moves, which contributes to playfulness. And variance in a system tends to contribute to a variety, novelty and excitement.

That is not to say that Skill Compensation is irrelevant. Some players may play games “to prove something”, in which case this might be a highly important property. Otherwise, such players may find themselves feeling cheated or having “wasted time” in terms of evaluating their skill/progress. Also, having lower Skill Compensation tends to lower the rate at which players will learn/gain understanding about your system. Whether this is important to you as a designer is a topic for another day. (Keith Burgun has claimed that a fundamental value in strategy games is gaining understanding, but it seems to me to be unclear whether the rate of this learning is important)

One thing I’d like to mention before closing is that games can also give feedback within a match (like taking a tower in DOTA), reducing your opponent’s life points in Magic or fulfilling an objective card in Wingspan. The extent to which this feedback is valid in terms of contributing to your win-rate is also interesting, but beyond the scope of this article.

To summarize, it is absolutely possible to have a game with high depth (interesting decision space to explore) and low Skill Compensation. Varying Skill Compensation can have both positive and negative effects on your game design, depending on what other properties you’re optimizing for (evaluation, learning rate, playfulness, etc). In addition, some players may find one range or another of Skill Compensation to be incompatible with their tastes. 

Let me know what you think, and whether this brings to mind games as examples of extreme ends of this spectrum, but with variable other properties. If you’re interested in games made with these sorts of considerations, especially with an eye towards playfulness, please sign up for the BrainGoodGames mailing list here.


* Notably, human performance can vary quite a bit from match to match even in a game that is very high in Skill Compensation, like Chess or StarCraft (there are other human factors like framing, specific preparation, nutrition, intimidation, etc etc). Therefore it might be more useful in some contexts to talk about performance within the frame of a given match rather than talk about player skill as an absolute fixed value, but we can use skill as a rough shorthand for average performance.

The “Playfulness” Property of Strategy Games

I’ve been thinking a lot lately about the properties that I appreciate the most in strategy games, and going through my collection of games I noticed a trend about my favorites. They all exhibited a high degree of an element called playfulness (term suggested by Keith Burgun, we talk a bit about it on his podcast here. Alternative names might be Smooth, Easy, Intuition-Rewarding and Streamlined)

To describe the property, let me first use a counterexample.  There is a common design aspiration to make games “simple to learn,but hard to master”. Games like Chess and Go embody this; they are both simple to learn (they have low inherent complexity/few rules) and hard to master/deep (they still exhibit a varied and interesting strategy space after a ton of intense study and play).

On the other hand, Caverna, StarCraft and Keyflower are quite complex and deep, but in my experience also don’t lend themselves to playfulness. In StarCraft, it can often feel like you are on a knife’s edge, and one wrong move can send the game spiraling out of control. In Caverna, it can often feel like there are large amounts of information you could be studying/calculating (like the building market), but don’t because it is overwhelming or tedious. (This can be a big problem if other players don’t mind the calculation).

So I’m not talking about simplicity/complexity, and I’m not talking about depth. (Although depth is  another property I aspire to in BrainGoodGames)

Instead playfulness refers to a property of games that encourages players to play with their gut/creatively, and minimizes the incentives to calculate/count/solve. Games that have this property include Race for the Galaxy, Wingspan and The Castles of Burgundy.

Race for the Galaxy is quite complex, and notoriously difficult to learn to play, but when I play I am often playing by feel rather than calculating out card probabilities or doing a lot of calculation. I think this in part can be attributed to the fact that you know some of the properties of the draw deck but not to an exhaustive degree.

The Castles of Burgundy also has quite a bit of inherent rules complexity, but gains a lot of playfulness by utilizing something I like to refer to as an “action funnel”. There are a ton of possible varied game states, actions and effects possible in the game, but on your turn you are constrained to actions that correspond to the values on the two dice you rolled. In this way you can focus your attention on a smaller part of the game system.

This player only has actions for a “3” and a “1” readily available to them (they can adjust them, but at an efficiency cost, so the heuristic to just focus on those values can be useful.

Wingspan also features an “action funnel” in that there are only 4 possible “main” actions available each turn (play a bird, or activate one of 3 habitats). In addition, it also features a system of “sub-goals” like “collect a bunch of birds with large wingspans” or “be the player with the most birds that have eggs on them”. It also features “sub-goals” on the bird cards themselves, such as a bird that encourages you to play birds with a certain nest type to gain more eggs.

“Sub-goals” on cards is also used by the 6-cost development cards in Race for the Galaxy, with similar effects. Players that are lost in the complexity of the game state can use the “sub-goals” as ready made heuristics to circumvent calculation and aid decision making. The labor-intensive process of picking through the huge decision tree can be circumvented with the expectation that the “sub-goals” are at least sometimes reasonable to pursue. (As the player plays more they can replace this rough heuristic with subtler/more context dependant ones)

Here are a few other game design techniques I have thought of that can contribute to playfulness (i.e encourage players to play with their gut):
Turn timers/real time games
-Simultaneous actions/”Yomi” mechanics/Donkeyspace
-Information horizon/ambiguity engines
-Trying to not punish player’s mistakes too harshly
-Increasing the complexity threshold until players give up calculating
-Using systems amenable to pattern recognition/chunking
-Avoiding snowballing mechanics
-Allowing risky play/”going all in”/comeback potential
-Thematic nudges (suggested by Keith Burgun) like having a cute, playful or unthreatening theme

I plan to elaborate on some of these in future articles, but hopefully you get a sense for the concept and why it might be useful to optimize for. I’d be very interested to hear any ideas you have about techniques for maximizing playfulness so please leave a comment, drop by the discord or tweet at me @brickroaddx. If you’re interested in games made with an eye towards playfulness, please sign up for the BrainGoodGames mailing list here.

Three Small Updates!

Did three small patches/hotfix updates this morning!

Militia 2 1.01m
-Added endless modes!
This one goes out to you Lord Gek!

Solar 1.07b
-Fixed small visual bug in card collection (deep space cards showing up twice)

Rolling 1.02b
-Moved second dice row down a bit to make it easier to click on the quick sun buttons

Working on an action-game type prototype right now,  which would be a first for BrainGoodGames! We’ll see where that goes, I’ll keep ya posted 🙂

Have a great Tuesday.

Militia Patch 1.01k is Live on Steam

Patch notes are here!

Polish update for Militia 2, and the final thing on the BrainGoodGames list before hunkering down with some new prototypes.

Future possible expansion ideas for Militia 2 are currently some “god” tiles like in Minos Strategos randomly added to the Weekly Challenge, “Endless Mode” and a “Daily Climb”.

Have a great Wednesday!

Solar Settlers Patch 1.07 and Rolling in the Reef Patch 1.02a are Live on Steam

Patch notes are here and here!

It was cool this week to be able to go back and dust off the cobwebs from both of these games after the Militia 2 launch (I have another update planned for that in the near future too, then back to NEW STUFF).

I feel very fortunate to be in a position where I can go back and tweak the games. It would feel pretty bad to have to leave them in a state I wasn’t 100% proud of.

As always, let me know if you have feedback about either of the patches or encounter any bugs or whatnot. And if you want updates when we release new BrainGoodGames and large updates for old ones, sign up for the mailing list here: https://braingoodgames.com/email.html It’s hugely appreciated!

Thanks for your support and for playing BrainGoodGames!
