Hey, thank you for your answer , it helped alot . I am getting dayz :)

So me and my buddy are planning to buy either arma 3 or dayz (1 of the 2). We'll be probably playing the game that we will buy until summer 2015 because we won't have free time after summer.We were looking for a survival game but i've read a lot of posts saying that dayz is buggy and slowly developed and that there are some arma 3 mods pretty similar to dayz. So What do you guys think?What do you suggest? Thank you :)
