Quote from: KitaruWait a fucking second.... *go check* ok I figured it out... world rule vs classic rule... Classic rule got the right T orientation. At least the one I am used to.
Actually, it's Blue Planet Software/The Tetris Company to ask about that particular change rather than Nintendo. (In fact, GameBoy, NES, and SNES Tetris all match the entry orientations that Sega used.) As for why... well, in some ways it's a long story. But, the short version is that various designers worked on versions of the game independently and each came up with slightly different sets of rules. So, not everyone followed the same set of traditions.
Problem solved xD
