While Skate 2 does have a decent number of improvements and additions over the first game, it is definitely still Skate. Anyone who played the first game for any amount of time will immediately feel right at home. Frankly, GamersReports did expect a bit more of a different experience when they put the game in, but it is certainly not a bad thing that EA did not change things drastically.
The developers basically took the complaints and requests that resulted from the first game, and used them to create this sequel. The game is worth picking up, especially during this beginning of the year lull.
