I know a lot of people swear by Tetris DS, and The New Tetris gets a lot of praise for its soundtrack too, but there are like a billion others. I'm curious as to which version everyone here likes the most!
I've been playing a bit of Tetris DS lately, and all of its extra modes kind of just make me want to play Standard Mode. And as far as I'm concerned, there's one game that pulled that off best:
Although I haven't played the NES version. That one looks neat.
Tetris Axis currently. Whatever version most people are playing during any given generation, I suppose. I'm not beholden to any one in particular. Though I do have some great nostalgic memories with the DS game.
This! The New Tetris always felt really well done to me. It's got great theming, terrific 4P modes, and the really excellent addition of Gold and Silver blocks (maybe the only Tetris addition I've played that I really think adds to the core game rather than detracts). Oddly enough, I'm a little ambivalent on the soundtrack--some of it's solid, but most of it is a little too weird for me. Trance isn't really my favorite genre of music.
A close second is the Game Boy classic. Still fun to play today.
Third is Tetris DS. Great multi and online and I enjoyed the theming and extra modes. But man, that infinite-spin mechanic is just the most horrible thing. And it plagues all modern Tetris games. I hate it and I have no idea why they keep putting it in games. It'd be like if every Mario Kart after DS had snaking.
While I personally adored most of the soundtrack (Giali especially) and felt it made the game super gnarly, one of the coolest, niftiest, most gratifying feelings in a Tetris game came from the sound effect when one quickly locked a piece into a very tricky, tight spot. So cool. It made me feel like a Tetris master... When I most certainly wasn't. I wish this game would hit the VC at some point. It and Tetris Attack are the best, and those I'd like to conveniently play once again.
I don't think Tetrisphere counts, so I'll say Tetris DS. I really like some of the modes in that, like Catch. So fun.
The worst version of Tetris has to be Tetris Worlds on GBA, so terrible. A close second would be The New Tetris on the N64 though, that's pretty bad too. The lack of a scoring system, the slowdown in multiplayer, and the awful soundtrack really kill it.
