The I of the Dragon. I wanted that game because it had dragons in it, but now I know better.
Bubble Bobble for the DS. Never buy that game for Heaven's sake.
Harvest Moon DS. The concept sounds fun, but gameplay progression is slow and dumb and it has so many bugs that I wonder if it's playable to the end, that is, to when you get sick of it and poison everybody with a lvl. 100 poison mushroom.
