Tetris Evolution Early Impressions

Ok, I bit. They releasedTetris for the 360 as a full game(ie on a disc) though one would guess it to be a prime candidate for a Live Arcade release. At least it only cost 30 beans, the idea of paying 60 for any game makes me choke. I'm a fairly big Tetris fan and played a lot of it online with the DS release. Tetris Evolution offers online multiplayer as well but I am yet to venture there. The presentation is quite impressive, flashy menus and all that - but you can tell they're stretching for content; The play area consists of less than a fifth of the screen and the rest is filled with a hi def looping video of your choosing(which there are quite a few of). Some of the available background music seemed way off the mark with grinding guitar riffs and generally aggro feel. Luckily mellow alternatives are available. I hope there are at least other styles of blocks to unlock. So as you can tell I haven't played much of it yet. I'll update with more info.
