When you see the 44 metascore you might think this game is broken, but if you actually read the reviews you'll find out that the reviewers always complain about the same 3 issues:
1st, they were too dumb to notice that this game is NOT a simulator, it's a mayhem arcade (a kind of 3D Rock 'n' Roll Racing). So, complains about the "unrealistic physics" are just stupidity. It's like complaining that Mario Kart is not realistic!
2nd, the game is too short. Now, it is true that there are too few tracks and too few cars, but the game actually runs very well with no bugs at all and it is actually fun for some fast destruction racing with friends.
And 3rd, the graphics are not top quality. But in my opinion, they are good enough. (Actually, I just can't understand why people give so much importance to graphics on games. Fabulous graphics may impress you at first, but after some minutes you get used to it and your entertainment will actually rely much more on other aspects, not on the graphics, unless it's so bad that it hampers gameplay, which is rare and definitely not the case here)
Though there are better titles out there, it's 44 metascore is simply absurd. This is not the first time I see a totally misleading metascore. I can't trust it anymore after this one.
