I'm playing Tales of Phanasia right now and the game looks really good and kinda impressive.

In my personal opinion, Com was pretty good for a GBA title, and Mickey's Quest looked good as well, even doing a layer look with backgrounds and stuff.

I'd have to say the best I've seen was Castlevania: Circle of The Moon. For a GBA game, it was impressive.

I'd say Mario & Luigi: Superstar Saga. That game has some impressive graphics imo.

Fire emblem had some amazing sprite work of it's time and it really just appeals to me, I can't really think of what can top it

I might have to say the Donkey Kong Country series.  I'm very impressed by the design of the worlds and the artwork.  There's other good ones as well, but they're not coming to me off the top of my head, sadly.

Oh, yes, those graphics were incredible.  I just love the Fire Emblem series. : )

I think Yoshi's Island. Even though the art style was simple, the graphics were rather colorful and the effects were fun and silly!

I'd say Mario & Luigi: Superstar Saga. That game has some impressive graphics imo.

I agree. Even playing on my VBA emulator in class (lol, yes I do this), I notice that the graphics for Superstar Saga are amazing. The gameplay supplements those graphics pretty well too! 

i'm not too familiar with many GBA games but i thought the Donkey Kong Country games looked pretty good. Also Chain of Memories, especially for the few FMVs that Square included.
