Just purchased the public Alpha version of Arma 3 on Steam and awaiting download. I know it will buggy as hell as Alpha but then all the Arma series have been and I still enjoy it. Lots of people moan on about the DCS series which is released in a similar way, buy into the Beta versions and they improve over time through patching. I think its a good idea, as a fan of these somewhat 'non commercialised' simulators, releasing Alpha and Beta's give the developers good cash flow to develop the game, if we had to wait only for a finished product, many of these developers wouldnt make it. And as I cant see another Arma 3 thread around here, have this one for starters!
