I really liked Tetris DS. The retro NES graphics and remixed music was a fantastic love letter to those old games, and the songs were pretty damn good to boot. It was also the version of Tetris I was best at, for some reason I was a lot better with the old, flat, firm DS Phat buttons more than any other console. I forgot what level I got to in Endless but it was probably over 500. Multiplayer was also a hoot, with powerups and you could play with 9 other people that didn’t even need the game to play. (Remember those days when you didn’t have to all have a copy of the game to play together? What a concept!)
In this case, “ass” is a funny oversimplification. The player model is on the screen all the time, so having it be attractive adds to the visual appeal of the whole experience
