I'm thinking about gettin a GBA SP so I can play some link up games with some friends, but I need some good recommendations first. I haven't played any good link up portable stuff since 4-player Warbirds on Lynx. Only thing I've seen that I'm interested in so far is Advance Wars, that is right up my league, but I would like to get a Mario Party type game for 4 player if possible.
I'm not interested in recommendations for RPG's or Sports games, but put em down if you want, other people who read this may be interested.
