Spider-Man 2 is a decent free roaming game, but the annoying side missions lets it down. Stick with GTA.
Good points are the fancy moves on offer, which some can be fun to do, whislt others are a waste, as they only make you swing faster or help you get to a loaction faster. The replay value is fairly decent, but after completing the game, you can only do the side-missions, which lets this game down big time.
Bad points are the camera can play up, and the annoying side-missions as well. The narrator is annoying to, I mean, do you need both on screen instructions and a narrator telling you what is what.
Spider-Man 2 isn't as good as everyone makes it out to be, and if you've played GTA, you won't be very keen on this.
