I only played Paper Mario TTYD. It was a great game: the maps, the battles, the badges, the storyline, Bonetail, et cetera. I stopped playing it after a while since there wasn't much left to do except go into the Pit of a hundred trials. I managed to reach the bottom about five times I think, and beat bonetail all but one time. Bummer that he doesn't anymore once you beat him.
...Why isn't the Po100T not on the poll o.O?
Also, I retired the game in level 35ish, and my yoshi was the color black.
