So I am planning to get a PS2. Problem is that I don't know which model to get. Some say that Phat is better while others say otherwise. Also I plan to get roughly 15-20 games for this PS2, so what size of memory card should I get? If you must know, I'm getting this PS2 to primarily play Kingdom Hearts, Final Fantasy, Tales series, Metal Gear Solid, Fatal Frame, and few more games.
