Ok, don't get me wrong, I love the Tetris game itself, but really the screwed this one up. The point of Tetris was simply to last as long as possible, getting as much points as possible. They eliminated that by actually having a final level! I know eventually, the difficulty stops going higher, but people tire out and make mistakes. In addition, if you move a piece and rotate it, it never sits. I played for a total of 3 hours, and I was board. I got more then half the achievements purposely getting only one. For hardcore Tetris fans, or experts, this is not the best game to go for. If you want a challenge, get a GameBoy, with an original Tetris chartridge, there is a challenge!
Now, for people getting into the game, this version is great because it allows a easy way into it, where before either you spent the time getting used to the concept, or you just didn't play it.
Now, what They have to do is do something like New Tetris that came out on the Nintendo64. That version was awesome, port that over, add Live play, and a few new modes, and that would be PERFECT.
This review is the opinion of myself, no one elses. You may feel free to disagree or agree with it, as long as you don't bash ME personally for having this opinion I don't really care.
