After Rockstar Vienna was closed down, the founders started a new company called Games That Matter. In August last year they were acquired by Koch Media and they are now known as Deep Silver Vienna.
Two of the projects they have been working on have recently been announced: Cursed Mountain, a survival horror game for the Wii set in Tibet, and Ride To Hell, a free-roaming action game for next-gen consoles and PC, set on the US West Coast in the 60s.
As Deep Silver Vienna uses a development model that's heavily based on outsourcing, they are much smaller than in the Rockstar Vienna days. It will be interesting to see how well these projects do: there are very few console games being made in German-speaking countries, let alone in Austria.
