It's true to say there's not much to it at the moment unless immersing yourself in the lore and facts is your thing. The flight sim, racing and combat are pretty basic still but I do have a play every once in a while.
I'm still expecting the final game to be awesome but it's a long way off. To put it into perspective, I started playing DayZ mod in end of summer 2012, people were expecting a standalone by that christmas, it's now 2015 and the DayZ standalone is still far from complete.
