I'll have to jump on the Virtual Boy bandwagon here (proof, as if it were needed, that innovation isn't always a good thing).
I'll also have to give mention to the games with 'Wii' in the title like 'Wii sports' and 'Wii fit'. From what I've heard they're just an assortment of mini-games and rainy day activities.
Finally, mention must go to F.E.A.R and it's spawn. Three words that summerised those games were: repetitive, dull and dark. I'm dreading the day when F.E.A.R 2 comes out (I've heard they're making it).
