If you don't have a PS2 get the PS3 with backwords compatability. PS2 has some killer games. So does the Wii... but the PS2 games are cheaper.

Actually, on second thought.
Get a Wii AND a PS2. That's an even better gaming value then the PS3... and I'm pretty sure it's cheaper then a PS3 with backwords compatability.
