lol, you guys are getting off topic with the M&L superstars (although i do love it, and paper mario 2 looks cool, even though i never played it for n64(maybe i should go and buy it?))

well, if you want to sell your ps2 to get more money to pay for xbox, then go for it
all i see going for xbox is online play and minimal good exclusive games, most other games can be found on other systems, but with slightly inferior graphics, and thats about it
your so set on getting, then nothings going to stop you from doing so, right?
unless you posted to hear our opinions on your situation
id say, if you have money, dont sell the ps2, just keep it
just dont play with the ps2 online and use your new xbox for all your online play, keep the ps2 for the rpgs
