Thanks for the input guys! Whilst almost every game mentioned has been one I've played, here is some feedback.
Bioshock 3 - It was better than 2, not as good as 1, they tried too hard to make the story complicated to get the twist the first had. The first was a simple, HUGE twist. 3 was just OTT. Plus, the lack of plasmids reduced the combat fun for me a little

What's not to like freezing on splicer, setting the other on fire only to jump into a pool of water. While smashing his buddy to tiny bits then turning back to the freshly watered splicer and zapping him with electricity... Combat gold.
Far Cry 3 - Loved it, however I got bored about 1/3 of the way through, it was very repetitive... I found it was anyway.
Bulletstorm - Completed on the 360, awesome game haha.
F.E.A.R - I don't do so well with scary games.
Shadow Warrior - No idea! Will look into this.
Serious Sam - Never played a SS, I picked one up in a recent humble bundle
Borderlands 2 - Got to about 1/2 way through and just lost interest... Not sure why.
Crysis 3 - Played the first parts of it, annoyed me I couldn't play it maxed out so didn't bother playing haha.
The Walking Dead - Bored me very quickly.
Dishonored - Great game, for some reason I was pulled away from it (another game maybe?), tried to come back to it and just can't seem to enjoy it.
Metro Last Light - Played a few hours, enjoyed, never went back to it.
Darkness II - Almost complete this on the 360.
So yea! I think I need to give a couple of those a second chance.
