Dude, Freakout is pretty fun. Three axis of rotation put this game above any snowboarding/ski game I've played so far. Yes, you can get 500 feet of air and stick quad inverts, but come on, its a video game! And with skill, you can do some steezy shit in Freakout.
Besides, do you think this freerunning game is going to be realistic?
Freakout is great, give it a shot and tell me its not fun.
