Accessible Japanese exclusive Game Boy games?

[cartman]

Well, define "accessible" for yourself. Even RPGs are playable without knowing Japanese with a little effort. Are you looking for games that completely lack Japanese text, or is there a certain amount you'll tolerate?

A little effort? If i know nothing about the story i don't see how they can be played at all. Sure i can run around and accidently do the right thing, but what kind of gaming experience is that?

The ammount of text isn't the most important, but the fact that the game can be played without understanding it.

I recommend TwinBee Da!, although I would suggest the colorized version available only in Europe over the b/w version available in Japan.

TwinBee Da!! was released in Europe under the name Pop'n TwinBee.
