Previous generation game on the current generation console...
Graphically, the game looks last generation, with low resolution close to regular XBOX (1024x576 on a wide screen TV, whereas XBOX has had 640x480 on regular 4:3 TV). The developers claim that they prefer the framerate over the prettiness of the picture, but come on! You've all seen what PS3 can do - you've all seen Uncharted, haven't you? Uncharted runs at great framerates, at full 720p resolution, and it looks gorgeous! So we all know PS3 is a very capable platform - how in the world, then, do you make a game, that can only squeeze decent framerates out of it, running at such a low resolution???
Personally I would recommend you either rent this game, or wait until you can buy a used one. I wouldn't pay more than $20 for this title.
