1. PS2
2. Gamecube
3. GBA
ps2 is my favorite because of the wide selection of games that appeal to me and it has my favorite controller. gamecubes rules because it has the best first party games for any system IMO. gba is just pure portable greatness.
now as far of the xbox goes, nothing about it appeals to me. i dont care about graphics (1998 is over) and i have NO desire to play console games online. and xbox doesnt have one single game that i want, i hate rpgs, sports, (console) first person shooters, flight, racing, and ninja games. its a shame all the good xbox games are in genres i dont like. i would like to see some original first party action/adventure and platformers on the xbox, then i might consider buying one.
