Wow. Thanks for all the replies.
Yes, I am quite concerned about Sega games (Meaning I want MORE, Dammit!). The PS2 never really struck a chord with me, I was just looking into it anyway. The Cube has brought some attention to my mind (Ok, Ok, Sega brought the Cube's attention to my mind.), but almost only becuase of Sega games. Then again, my friend (who has a Cube.) does have the games for it that most people consider to be sucky (Namely: Luigi's Mansion, Pikmin...). Of course, Smash Bros. Melee and Monkey Ball are genius...
However, I still seem to lean toward the Box. Isn't PSO on the Box too? PSO, all the other Sega games, and the games that other companies are putting out (Some are quite good.) all kick ass.
To the person that suggested postponing the system, I was actually making this as a Christmas descision. Since my parents aren't buying me shit, Im going to get myself something. That something (right now.) looks to be an X-Box.
Well, I'll keep looking into the other systems!
