What are the best GBA games?

[Swingman]

I'm getting a DS for christmas with Mario Kart DS and Nintendogs.

I am thinking of picking up some cheap GBA games and wondered what I should pick up.

I definitely want to pick up one of the zeldas to hold me over until DS gets one just because I like Zelda a lot.

Legend of Zelda GBA (port of NES game) - $10
Zelda: A Link to the Past GBA (port of SNES game) - $20
Zelda: Minish Cup - $30

For the most part I don't want to get GBA games that have (or will soon have) DS sequels.

Not a big fan of Animal Crossing (I know that's blasphemy) or Pokemon. I like shooters, RPGs, sports games, platformers (ie Super Mario Brothers) and adventure games.

Get your ass some Mario and Luigi, once you finish it there should be a decent sale on the new Mario and Luigi for DS.

Fire Emblem... Fire Emblem Sacred Stones is good too, but I like the first one a lot more.

edit: dont forget Super Puzzle Fighter!!!!
