Not sure what I think about how planets only have a limited amount of tiles. I mean, they are
planets. Tiles is something that makes more sense when building a city or something.
I by far thought Stars!' approach, where you could build as many factories or mines as you wished, but each mine and factory needed a certain amount of people to actually run them, made much more sense. If you have a whole planet to build on, what's limiting you should be manpower, not running out of space. Not being able to build in mountains, for example, makes sense, at least for certain specis, but tiles? Nah. Just makes the game feel unrealistic to me, and breaks my immersion.
