ACE - When people come up with something good like ARMA II, they want to give the fans more. Sometimes, that means a full blown sequel. Sometimes, it's an expansion pack, and Bohemia Interactive decided this was the way to go. With Operation Arrowhead, they give us some new goodies which were missing for one reason or another in the original game. At the same time, they take away the tight storyline focus that made the base game so intense.
