A gaming console manufactured by Sony. It has the most marketshare and in general has the most games avalable that will appeal to the widest audience.
The alternatives to the PS2 offer more specialized games. For example, the Gamecube has excillent first party support and has some of the most outstanding average of games and graphics on the market, and a ton of shitty ports of other games. The Xbox on the other hand is for people who prefer graphics over any actual gameplay.
I just got Amplitude for PS2! Damn that game rocks!
