Is the GBA Worth Getting?

[Mr.Nobody]

I've been thinking about buying a GBA.

The games I am interested in are: The Castlevania Games,The Golden Sun games, Final Fantasy Tactics Advanced(Is that what it's called. I don't remember)Advanced War,Zelda:Link To The Past(I never got it for my SNES),Super Mario World 1 & 2(Those ports of the SNES games. I really would like portable versions),and Megaman Zero(And future Megaman Zero Games),and Metroid Fusion.

Are there enough other good games to make this a worthy purchase?

Thanks in advanced.
