Inventor of the real-time score-attack puzzle game (as far as I know) and when accounting for its million quadrillion versions, probably still its king. To be honest, that's not something I can confirm. I respect these plenty, but on the cosmic scale of all video games, this is unavoidably the genre by which I am the least compelled. Is Tetris better than Puyo Puyo? I have no idea. What I do know is that Tetris matters, and that it's good.
