Only 2?!

1.} Absolutely Auto-Hide chat log. It makes the screen so much more clean and you really get to immerse yourself into the game when its doing its own thing when people are quiet.
2.} Quality cutscenes. If 1.0 did anything right, it was their cutscenes. The 1.0 development team clearly loved their game. Unfinished, and a mess, yes, but loved very dearly.
