So I bought a new GBA off of Ebay last week and thinking what should be my first game for it (I already own a GBC and have some games, so I'm looking at GBA games for the most part)
Wario Ware Inc. is a really addicting game. All it really is is a crap load of mini games. Then there's Advance Wars, a fun strategy game that's similar to Final Fantasy Tactics (you should check out FFTactics Advance, never played it but I hear it's great) or Front Mission. There's also the Castlevania games which are pretty good.
And there's the classic SNES games like the Donkey Kong Countries and Zelda.
If you ever played Kingdom Hearts for Playstation2, you should get Kingdom Hearts: Chain of Memories. It's a link in story from the fist one to the second one (which is coming out is a few months, I think).
Yeah the Minish Cap is for the GBA. Oh and I also finally beat Ocarina of Time, took a long break (somwhere amoung alot of time) thx to the Water Temple...then dug it out and beat the last of the temples.
Also some other games where Final Fantasy I & II: Dawn of Souls and Golden Sun.
bet the Master Quest (Ocarina of Time remake on the GC, added stuff, harder dungeons I think) Water Temple is impossible to a power that makes numbers looks small.
