Also, like, seven Dragon Ball games.
And I'm just teasin', man. You can like the GBA all you want, but in literal facts, it wasn't anything incredible in terms of what improvements they should have started out with in the time frame.
So, a quick glance over the GBA release list, I assume everyone else's idea of "must haves" on the systems included: Advanced Wars, FF Tactics, Mega Man Battle Network and Mega Man Zero, Mario & Luigi, and possibly the Wario Ware games. Am I close? Because I don't own any of those games (no appeal to me).
