In SkyBoats there are a number of different upgrades that ships can start with, and that can be purchased at the SkyCities. These upgrades give boats different powers in place of a basic fuel providing cargo hold. The basic cargo hold in SkyBoats provides one fuel if used when empty or it can use the wind creation power of the good inside the hold. Most of the SkyBoats start with one upgrade.

When we were designing the upgrades we wanted to come up with mechanics that could be easily learned, but would provide players with a lot of different ways to use them. A lot of these upgrades are related to movement around the board. For example, the blink upgrade allows you to jump over a space, which can be useful to avoid a wind blowing a direction you do not want to follow. The blink upgrade can also be used to grab goods a little distance away and blow back to where you were, or to get yourself onto a long wind pattern to increase your wind meter! We aimed to create a number of different upgrades which can all be used in a number of different situations.
Finally, we wanted the upgrades to function together to create even more interesting choices. We believe that this system creates a lot of interesting decisions to be made by the players, without adding a ton of complexity to the game. It is always a difficult balance between complexity and depth. I think the upgrades we have created do a great job of using up a small amount of complexity, while creating a lot of strategic depth.
