I played SM2 on the PS2, cool game, but the camera view is too far (it's like the farthest view in GTA, only one camera) from Spidey to get the sense you're playing the character, not just watching him swing around. The controls are choppy walking around, but the unlimited jumping, web-slinging, climbing and reaching the tops of every building is cool. Some of the missions are really tough, like the statue of Liberty one high above the water. It's worth a rental if you're a fan of Spider-Man.
They're working on Spider-Man 3 for the next gen systems, PC.
