Tetris Battle Gaiden was developed by Bullet Proof Software, which was the studio founded by Henk Rogers, otherwise known as the person who helped bring Tetris to the world in a partnership with Nintendo. It was published by Bullet Proof Software, as well, and remained exclusive to Japan on the Super Famicom. A huge shame for a number of reasons, like the fact that Tetris was a worldwide phenomenon, and that while there was text in Tetris Battle Gaiden, it\u2019s not like it was a role-playing game with a lengthy script that needed an obscene amount of time for localizing. But also because there\u2019s nothing quite like this spin-off out there, as anyone who has played it can attest.
