What kind of games does she like? (Score 1)

If it were me, I would have to go with a GameCube. Even though it has few games with native online support (I think just PSO), there are games with LAN support you can play over the Internet using Warp Pipe. MarioKart, which my girlfriend loves, is one of them. Super Monkey Ball 3, another game series my girlfriend loves, will have LAN support when it comes out. Lately we have been playing Baulder's Gate: Dark Alliance II on the PS2, which does not have LAN support, but since she likes it, maybe she would like PSO. I am not familiar with PS2 or X-Box online gaming, other that knowing that they both have headsets, which may or may not be what you want. Actually, if you liked GoldenEye 007, then TimeSplitters 2 is the next best thing, but it only has LAN support on the PS2 and X-Box. Hopefully TS3 will have LAN support on the GC too.
