Thanks for the heads up. Prefer getting it from GamersGate than Steam as there is less hassles with mods and updates. Coming from a smaller foreign developer I would not be surprised if there were some delays with updates for the Steam version compared to the retail version. A downloadable version from GamersGate (or the Bohemia Interactive store) is essentially the same as the retail version and will update using the same patches released by the developer for retail copies.
