Final Fantasy 12, which oddly though, is one I really like. It's a straight Star Wars: A New Hope ripoff, but at least the plot is understandable (at least up to the point I played). I actually enjoyed it compared to the other insanities that are a Final Fantasy game, but for some reason I just couldn't stay interested in it, and put it down every time I tried to play it.
Prince of Persia: Warrior Within. I got to the point where they introduced the villianess with a full screen closeup of your metal thonged ass, and I was like "....ok nope, not playing this, I'm not going to like this at all." Coupled with the horrible metal music, instead of the cool Arabian-esque music from Sands of Time, yeah, screw that game.
A game I almost put down and stopped playing last night was FTL. Kept having trouble accomplishing anything in that game, so I bumped it down to EASY difficulty....and died on my 2nd jump. That almost made me punch my monitor. But, things got better, as I finally unlocked a ship that's worth a damn, instead of the default one, so things are going better, a bit.
Archeage. Was in the most recent Beta, and got annoyed with the game after about an hour of play. Uninstalled, and don't plan on checking it out again.
