Trilarion: Somehow ironic that the users of "free, transparent, open" Linux have to rely on the "DRMed, put PC games in a cage" STEAM service to get their games. And the reason is that the Linux tribe is just too small to make the "marriage made in heaven" which the support of Linux by GOG could be seen as.
Well, we have Desura, the Humble Store and (for Ubuntu users), the Ubuntu Software Centre, so it's no like we have no choice, although Steam does have a lot of games on it that are Steamworks-only on Linux. The only way to get Strike Suit Zero for Linux for example is through Steam, although if I'm honest, the GOG version, which was the only DRM-free version available, was a clusterfuck without compare.
