I second FF XIII . I bought FFXIII-2 like a month ago thinking it would motivate me to finally finish the game, and I did make a little bit of progress, but now I've lost all interest again. Thinking about just cutting my losses and selling them both.
God of War 3 I really liked GoW 1, but it is the only game in the series that I have actually beaten ( which is pretty bad seeing as how I own every one of them)
Medal of Honor Worse then CoD The only thing I really like about that game is the sound effects
