I am looking foward to the ArmA 1 campaign being converted over. I hope it is still being worked on. Certainly having the islands will be nice too.
I always meant to play through the ArmA 1 campaign, but back when I bought it my computer couldn't handle the game. Years later when I got a new comp I didn't get into ArmA again until I downloaded the ACE mod. Great mod, but it didn't work well with the SP campaign. I tried to fight a nice assortment of mods to add better weapons, effects, tracers, and etc. comparable with the campaign but couldn't find anything that made the experience closer to that of ArmA 2.
So good luck CAA1 guys, look foward to seeing your next releases.
