Activison did it!!! They gave you the feel of web-slinging through the city.
Besides playing in a comic style enviroment, with both hero and villian the game also offers you other little extras, like appearances from other marvel heros and unlockables like the layout of some scenes in the game, and covers for the Ultimate Spider-Man issues.
For this game i would recommend you get a controller, unless you're double-jointed and have god-like reflexes on the keyboard and mouse, because the races in this game are freaking hard!!! It's a good thing the races are just side missions, so you don't need to do them to get the story going.
So, what makes this game great, i would say; the races, rampages with venom, learning new web tricks, and the combat tours.
What makes it not so great; the annoying bosses (like the green goblin 'burrrrrrrn!!!'), repetition (like some of the combat tours and chasing down a boss before you battle) and short story (the game can last about 7 hours or less).
All an all, the game is one worth playing then re-visiting, and rememeber; be patient with this one, don't expect to beat Johnny Storm on you're 1st try.
