Ok I got a few comments...
1. Gameboy WTF??? LOL Well I guess some people like it
2. XBOX has Halo 2 (The Best Game EVER!!!)
3. PS2 has GTA, but now XBOX has them
4. PS2 Controller way easier to use.
5. XBOX has built in "memory card"
6. PS2 online is free as long as you have broadband and the Network Adapter (I think thats what it is called LOL Not 100% sure tho) With XBOX you have to pay for online...
Thats all that I can think of...
