I really wish I had read these helpful nuggets of information before getting this game. I have to same that most of you are completely on the money here. The levels are dull and repetitive and the fly sections, well the flying levels smashed home the truth that this isn't a bad game for its age, its just a bad game period. Playing this on original xbox or PS2 would have pissed me off.
Thankfully I had rented this game but it still took over 6 weeks to get through the 20ish levels. Least the achievements were simple enough, but I can't even recommend the game just on that.
Hope this helps anyone else thinking about picking this up.
