For me, it doesn't matter how many wacky modes you build around Tetris. None of them can be as good as the basic original, and that core gameplay isn't worth $30 to me in this modern age, nor is it something I'm going to spend much more time on beyond the 100+ hours accumulated across numerous versions. The only Tetris enhancement I really care about is some kind of persistence, like building up lines in The New Tetris (N64). I also liked the mega-block feature in that game, and it's odd that the newer versions don't include it.
