Look, I'm not saying this game doesn't have its moments--because it does. You'll have times when you're laughing out of sheer glee because you just did some trick so insane that it's mindblowing. However, the Tony Hawk franchise is just becoming repetitive. It's the same game, over, and over, and over, and over again. Yeah, there's some polish, and yeah, there's new features.
Now, before you go thinking I hate the Tony Hawk series, I'm going to doubt you have a working N64 with Tony Hawk's Pro Skater, Pro Skater 2, and Pro Skater 3, and still play them from time to time. I still believe that THUG was the best incarnation of the Tony Hawk franchise, despite this.
Now then.. the game has nice graphics, retardedly insane tricks--as I just got through saying, and the exact same gameplay as in the previous TH games. Y or Triangle--depending on whether you're on 360 or PS3, or PS2 for that matter--is still grind. X / A is still jump. Square / X is still fliptrick. And O / B is still grab trick.
I won't say that the game is bad, because it isn't. However, I still believe the Skate franchise has a more intelligent design, and a far more interesting control scheme--when you nail your first 37 trick combo in Skate, you're gonna be like "HOLY. FREAKING. CARP. I CAN'T BELIEVE I JUST DID THAT." In Tony Hawk, you'll have done probably a 217 trick combo by that time. But, this is all opinion, as all reviews are.
Tony Hawk's Project 8 is by no means a bad game... but it's the exact same thing as the previous ones. (Also, if you're going "Psh, I doubt he even played through the game" .. I got Gold on all challenges and beat it twice. Though, I'm not one to brag. :P)
