Remember, you could always get the original GBA if cost is a huge issue, both systems play the same games. I would recomend the SP however if you have the money, since the built in lighting makes things a lot easier. As for games there are a ton, all the super mario advanced games, advance wars 1 and 2, warioware, the castlevanias, the metroids, fire emblem, sword of mana, Zelda, Harvest Moon and I'm sure I'm still leaving a bunch out.
