Sure they are chum.

1 of the 3, and BAD graphics is definitely a criteria for not playing a game.
The GBA doesn't have enough power to give you complex games, so it loses out on 2 of the 3 criteria, especially when trying to emulate other systems or use MAME. I've owned both, and the GBA is ancient and weak, the DS isn't bad, but the only part of the triumvirate that the GBA games have is fun/replayability, and that available on most gaming devices, or else they won't be used.
Show me a complex story 3D game on the GBA that even comes close to the dozens on the PSP.
Since you're so defensive about the GBA why not post these killer games you think are so awesome.
