There are plenty of people who are heavily into importing for the Saturn, Dreamcast, TG16, SNES, even the Playstation. But what about the systems that aren't known for having great imports? Is this simply because the Japan-only games are terrible?

I've been wondering about systems like the N64, Game Boy/Color/Advance, Sega CD, Game Gear, and others.

I have Kunio's Dodgeball for the Game Boy and it's pretty good...kinda slow compared to the NES Super Dodgeball though. I've heard good things about Annet Again for Sega CD...
