The GBA was heaven for people who like J and S RPGs. It (and I believe the DS) are the only systems to have managed to bring a

Eye of the Beholder, including a remake of that game, and a really neat game by a small South American studio called
Mazes of Fate. This thread is kind of making me want to fire up the GBA emulator on my phone. I'd use the actual hardware, but that would require me to carry it around with me, when I've already got my phone on me at all times.
