Completed Dying Light this week.  Had been playing a little every week for about 4 months now.
The first zombie game I played, I think this is the best survival horror game I played ( I usually don't like this genre)
+  The game looked awesome, had a sort of photorealistic feel, The story was decent & the gameplay was interesting, the upgrades are a lot of fun.  
-  I like to play easy games, this one was too difficult for me and had to use god mode on and off.  I mean even Crysis on delta is easier than this on easy.
