2007's crop of crap games
Aside from erroneously describing Lifesigns as a Trauma Center clone (Kenshuui Tendo Dokuta saw its Japanese release six months before Atlus' surgery sim), Pocket Gamer's ten worst DS games of 2007 excellently outlines which of this year's games you shouldn't spend your hard-earned money on. It has an even sampling of shovelware (e.g. MinDStorm: Train Your Brain and B-17 Fortress in the Sky) and titles with potential that fell flat on their faces (e.g. The Settlers and Lost in Blue 2) -- this way, you're not only warned of games that obviously suck, but of games that mask their severe failings until it's too late, as well.
