Several.
Velvet Assassin - No play value to it at all. You just walk around, stab things, and get shot. A lot.
Kingdom Under Fire: Circle of Doom - I played this for about half an hour, then stopped and never played again, and I've never done that before. That's how bad this is. The game is literally 100% button-mashing. The combat is probably the worst I've ever seen, and combat is all there is to the game.
Civilization IV - The game was given high ratings, and honestly, I don't know why. Of all the games I've said "I don't know why people think it's so good" to, this is the one that stands above all the others. All you do that I noticed, was just wait 10 minutes for a menu to pop up, click something, wait another 10 minutes for a menu, click something, and so on. I didn't notice any effects from clicking these options, either.
Dragon Age: Origins - Another "I don't know why people think it's so good" case, for the mediocre story, uninteresting characters, dull world, and the majority of the game being copied from other franchises.
Lost Odyssey - Not because it's bad, it's just infuriatingly hard.
Fable 3 - I got excited for this. Peter Molyneux made it sound like it was going to be the Holy Grail of games, but it ended up even worse than the previous instalment of the series. Nearly everything he told us about Fable 3 was bull. I'll just stick with the first Fable.
I naturally have a lot more, but I'm too tired to carry on. I'm gonna go to bed now.
I probably sounded grumpy in this post. Tired.
