Valve is on a bit of a roll at the moment, what with Portal 2 shattering critical and commercial expectations, and now its Steam service has helped boost Dawn of War 2: Retribution Sales by up to 129%. Previously, THQ had intended to go with Games for Windows Live, but then decided to switch to Valve's service, which saw a boom in coverage, culminating in a sales that far exceeded than their initial forecasts.
Dawn of War 2: Retribution utilizes many of Steam's best features, including cloud saving, in-game and lobby chat, a complex ranking system and, of course, Achievements. Originally planned for Games for Windows Live - which would have required both a GfWL account and Steamworks account - THQ was fearful they're switch might upset fans, but thankfully that was not the case. "There was a lot of concern the move away from our previous expansion strategy would fragment the community. Looking at the numbers, it's clear most active players have moved over to Retribution, and the total hasn't gone down". [Eurogamer]
