It's a pretty fun game and even more so if you have friends to play it with. I would recommend getting it.

I haven't played it in a few weeks but it seems like they have been releasing updates frequently.

Easily one of the best games out right now.
I play it on very low settings and get 40fps which obviously isn't the best but it does the job and it's playable without problems. I don't think the quality matters too much. You get used to it which is the good thing. You meet people on it too, so you will not be alone for long.

If you do buy it, please be aware of bandits and friendly players. When I first bought it I was killed by a guy with full military gear and I was confused because obviously I thought everyone worked together. You have to learn how to approach people and what to say, etc. Please don't get angry and quit if you die, takes time to get used to the game.

Or everyone running around without any walls or bushes destroying you, when it'd take 30 mins of coding to smash the bug.
