I'm currently caught up in playing Spiderman 2 (PS2). It's got less than stellar graphics, but there's no other game that makes you feel more like a superhero. The web-slinging is awesome, and the graphics had to be sacrificed to allow the no loading times, and the high framerate. I'm also currently playing Psi-Ops: The Mindgate Conspiracy (PS2). Slamming bad guys into walls with your mind never gets old, nor does controlling their minds, only to have them kill all their comrades, and then proceed to jump off a cliff. Both are definitely must-have titles, but I'd have to say Psi-Ops is more fun.
