If the price was the same, I think I would choose Standalone. But i still don't know, I mean, they are still working on standalone and one day this game will be awesome, I'm sure. The question is, when will this day come. How do you think? Will I have to wait a long time before this game will be better than mod? Damn, it's hard to make a decision :D But well, I think it's a good idea to buy DayZ mod now and maybe just wait for a sale to get Standalone, for example, when it will be at least in beta. One last question: Can I buy just Arma 2 or I have to buy Combined Operations version?
