From the same people as FTL, Into The Breach is one of the only games I consider a “perfect game” — there is almost nothing about it that could be improved without it just being a different game. I 100%'ed that game 1.5 times and it’s absolutely amazing.
It’s a turn-based tactics game with absolutely perfect interface (the way they went about its design is a whole interesting thing in itself); like chess but you only need to think 1.5 moves into the future.
