4. Mario Party 8, (No. 31) Nintendo

Mario Party sells bucket loads, but we can't understand why. We know the Wii is all about appealing to a wider audience with fun, casual, easy to get into party-style games, but we can't see Mario Party 8 appealing to anyone, even the masochistic, rubbish game-loving among you. The core gameplay is dull, the mini-games are uninspired and the presentation is terrible. There must be a hell of a lot of die-hard Nintendo fans out there willing to put up with pap just to get a glimpse of Mario and co. That's the only thing we can think of that explains how Mario Party 8 has ended up the 31st highest selling game.

3. Transformers The Game, (No. 22) Activision

Say what you want about the movie (we enjoyed it actually) but the game is undeniably pants. Reinforcing the classic movie licensed game will be terrible mantra, Transformers the game is as close to a steaming pile of cow dung as any game we've played in the last few years. That it's ended up selling enough copies to make it into 2007's top 50 is not only a travesty for electronic entertainment, but a travesty for the human race (and a triumph for game marketing and promotional movie tie-ins).
