There are a lot of great DS games ... but not all of 'em are worth going gaga over. In fact, some are downright bad. Luckily, we've got a lot of games that are good enough to balance out the occasional pile of poo, but we want to hear about your recent bad experiences. Maybe you borrowed or rented something -- or worse, had the misfortune of buying it -- that just wasn't quite up to your expectations. Help everyone else out and share your stories.
