If this is simply a paid mod for ArmA 2 AO I will skip it.
They would need to make functional AI that can hit a target 20 meters in front of them, a proper mission editor UI, vehicle AI that can stay on their waypoints on the roads without diverting and getting stuck on fences, weapon animations (no animations for bolt actions would be lame, immersion killing, and awkward) and a decent squad control interface at minimum for me to buy it.
Sadly, I think this will just be the case as with ArmA 2 and OA... just a tiny bit of improvements (that should have been released for free as bug fixes in ArmA 1, such as reloading while walking) but largely the same dysfunctional game.
It is a shame to.
I think you have this game confused with Codemasters Dragon Rising and Red River.

Not sure what you mean by dysfunctional game either.
I am looking forward to this as I loved the Libmod for OFP back in the day.
They are licencing the engine so maybe they have access to some features that are present in VBS. One can only hope.
