Probably one of the most mechanically perfect games I can think of. At first it might feel like your success is entirely up to fate, but as you improve you realize how much impact every small decision has. Climbing Ascension levels only deepens this level of connection with the mechanics of each character and of the game as a whole.

Probably one of a small handful of games that I could play endlessly, given I was trapped on a deserted island or something.
