Well, it's a hard one to say...
The motion control is the most controversial issue. I'm sure the game would have done better in reviews, maybe by 10%, if there were just the option for stick control. Given the option though, I don't think many people would opt for motion control since it does take some time to learn - and it's difficult to learn new things in stressful situations. That said, once I got into it I honestly do prefer the motion control for flight. I heard something about older PS3 firmware not supporting the motion sensitivity as well as the latest version, but I can't speak to that since we're all updated.
Can't say I'm happy with the reviews but really, nothing they are saying comes as a surprise. I was responsible for three of the levels and I'm proud of my work.
