Pretty much sums it up. While both ARMA and DayZ are fun enough to justify the cost, the stand alone is close enough that it's worth the wait. It's an extremely unforgiving game with a steep learning curve, mostly because once you learn how to survive/scavenge, the only thing left to do is either hunt friendlies, bandits or both. Having someone to cover you while you rummage through a grocery store instead of getting shot in the back looking for a can of beans is nice, too.
