Best GBA games?

[Smeags]

My GBA Favorites (aka: Teh Best! ):

Castlevania Series (Circle, Aria, and Harmony)
Mario & Luigi (I'm not much of an RPG fan, but I couldn't stop playing this gem)
Sonic Advance Series (Reminded me of the Genesis days of old)
Super Mario Advance Series (Each one is a classic)
Metroid Zero Mission
