I'm debating checking this game out.
My concerns are the bugs and the hackers. I can live with getting player killed. (I think) I have been checking out you tube videos and forums so I have some idea of what I would be getting into. I'm just thinking I may wait for the stand alone to be released. If someone has a strong argument for going for it now let me know.
I have played Arma 2 offline but never online mostly the quick single player missions.
