I downloaded Tetris. I was surprised by how 'advanced' it is. I was expecting something like the built-in games. It's full of colorful full motion graphics, along with sound effects, music, a menu with various options, various play modes etc. As for the control, it's a little tough. I think mostly I'm just not used to it. I'm not sure I would have used the scroll wheel. I probably would have made FWD and REV move the piece, the center button turn it, and the play/pause button drop it. As it is, you use the scroll wheel to move pieces, FWD/REV to turn them, and the center button and play/pause to drop pieces. Overall, it's quite nicely done, and while I don't plan to buy any more games from those currently available, I will consider buying other games in the future.
