Congrats Obi, I read that she's got a gamecube which is the ultimate pre-game while playing video games with women... Most of the games that are multiplayer are childish enough to keep them entertained and fun enough to keep us gamers entertained.
You can go with the typical Mario Kart / Mario games, but I'd suggest looking at Super Monkey Ball, which is a **** load of fun and I haven't met a girl that doesn't think it's cute and fun.
As for online emulators, I know nothing about that so I can't help you bro. But whatever you find I'd be interested.
Stay up player.
