While I do not know most of games (know means "played them eoungh to have solid opinion), I can discourage You from Dead Island.
Hmm, I had a blast playing Dead Island, over and over again. The amount of (home-made) weapons you can use on zombies (and the occasional humans) made this game to never grow old for me.
Even after finishing the game multiple times, I often found myself coming back just for some creative zombie killing R&R.
You'll have to like killing zombies ofcourse.
Far Cry 3, a good game, but in my opinion it has more repetitiveness in it than Dead Island. Yay, another radio tower to climb into. Hourray, another small enemy encampment to take over.
After I finished this game I didn't feel the urge to play it again, since there's nothing to do afterwards.
It was still a very entertaining game though, and worth it to at least play through the story. The Kick the Hornet's Nest mission is in my top ten of best missions ever. x)
Edit: The Saints Row games are pretty hilarious, judging from youtube videos. Might want to check those out too.
I've yet to play any of them myself though.
