Ever since my GBA got stolen, I've decided not to buy any more games (go figure

). But when the GBA SP came out I was thinking it was really badass; too bad it's 100 freakin' bucks! A little steep for something I would barely play.
Now that the GB Player is out, I'm interested again because it's only $50. So I'm wondering if some of y'all could tell me about some of the good recent games. The last games I really liked on it were Advance Wars and Golden Sun, so have there been any sequels? I didn't like really fast games like F-Zero or Mario Kart much on such a small screen, but is it easier on the bigscreen?
