In my opinion in order for Rocket to profit the most from this game is for everyone to wait to pay for the stand alone game, paying for arma 2 co does not give Rocket direct profits, since arma 2 has already increased there profits from sales made due to the fact, poeple want DayZ, arma 2 has agreed to help Rocket, so now that is taking place i think that the more people that can wait and pay full price for the stand alone game would be more benificial to Rocket and the development of the game!
