2 crashes on 11 hours of gameplay,here. That's good for a game that's just out.
Technically, this game works very, very well for me:
1. No stutter or lag whatsoever, despite the stunning graphics
2. Loading time is 1 or 2 seconds. Wow! Same small delay for entering a new area.
But I disagree with you about the interface. It's counter-intuitive and re-mapping the keys to the user's prefence appears to be very problematic.
