Really I just meant any console version of Tetris - NES, Xbox, etc.
Personally I agree about turbo being cheating, but I still wanted to hear people's opinions, or if anyone had ever heard of it being used it in a tournament or to set a record.
Speaking more about controls, do people prefer Dpads, Arrows/WASD (Keyboard), or Arcade Sticks?
Dpad is the staple for consoles. Chances are you've never even considered using an alternative if you play NES Tetris. Perhaps you use the Xbox Thumb Stick? But if somebody offered you a keyboard modified to work on a NES, would you make the change? Or do you still prefer the handheld controller, possibly being more comfortable for long Tetris sessions.
Arrow keys/WASD are probably the cleanest input method - you can have a finger to each button at all times, so there is less room for error (compared to the Xbox Dpad for example, where you could push up or do if you're not careful). Obviously most PC Tetris games will be played on this.
Arcade Stick is the standard for TGM. In fact, you can't use anything else unless you play TGM on an emulator. But if you could, would you swap your controller?
A final thing to consider is that all of these methods utilise different parts of your body - thumb for the Dpad, fingers for the Arrow Keys, and the whole hand for the Arcade Stick. Can this have an effect on your game?
