A new piece by Vivafringe talks about a common pitfall in some kinds of strategy games, using Fire Emblem as an example.
Fire Emblem mostly has a good, clean interface, but scanning for abilities is an annoying exception. A given character can have different abilities, and these can only be noticed by proofreading the tiny ABC circles in the upper right corner. If you don’t immediately recognize an icon, you need to longpress it to see what it does.
Try to avoid having long-distance interaction unless it adds a lot to your game. Make pieces more like Go, where stones can only affect adjacent spaces, than Chess, where a Bishop can threaten a square from across the board. If you do want a Bishop-like character, try to have the squares it threatens show up as dangerous in the UI, rather than forcing the player to trace all of its paths himself.
