Um, I've only picked up the halo games a few times and I beat 2 on legendary in one sitting. Didn't take long, just I had to be more careful.
I thought halo was good but got talked about too much. I was thinking the same thing for Gears of war but I hadn't played it so I couldn't judge it. When I did play it and I loved it.
Personally I'm not a fan of the more popular FF games. As in 6,7,8 and 11. I found that they were overhyped then when I did play them they didn't live up to the expectations everyone had set for them.
Any of the Need for Speed games. You drive around a track, fast. Not much too it.
Fable. Awesome game, way too short. Would have been better if they made it longer.
I liked X. I thought the sphere grid was a cool idea. I like XII, it's pretty and it doesn't conentrate on one character which most of you complain about all the other ff's. Which makes no sense why you don't like this one.
There's prolly more but I can't think of anymore right now.
