Same goes for me atleast on my work laptop.
If you could get it working you'd have 2 more testers here :P
Back to the theme, You'll need to have a sinister/gloomy look to the game in that case, Currently it looks too nice and innocent if you get what I mean.
Just as an example. It creates a good setting for the game.
Compared to Dayz yea that isn't sinister and gloomy but that game can use alot of other things such as it being first person, Empty land, Broken down cars etc. Different genres will have different things it can do to make it appealing.
