Also, all kinds of strategy games. Eg Europa Universalis 4, any Civilization game (even though they may look 3d these days, it's not why you play them).
Is there a practical intro somewhere? One that allows me to actually play a game, even losing it badly, but not encounter half a dozen "huh, I have no idea what that means and what I should do now" situations every turn.
It's worth it, though...
That's how people learn Dwarfortress, which is even less penetrable. Remember, losing is fun.
Exactly, it's a good example of a game that uses 3D only for effect, without incorporating it at all in the gameplay.
