PSX: Crash Bandicoot. That's a good part of my childhood in that series. PS2: The Bouncer. Not a bad game, I really like it. But it's quite challenging. PS3: Metal Gear Solid 4. I'll admit, this was one of the largest reasons I bought a PS3, and I practically played the game to death before I even touched another game. PSP: Persona 3 Portable. Good times.
