Hello there, I've been scoping around Arma II for a while reading what's it about and watching videos and I'm more than certain I want to buy both the actual game and get the mod as well. However, I told a friend of mine about my intentions and he told me not to buy it because of the huge amount of hackers both in the actual game and in the mod. Any thoughts? Should I buy it despite that? Many thanks
