Desura is a content delivery platform for games and mods developed by DesuraNET. In a nutshell, it is just like Valve’s steam platform. Currently, it has a very good amount of Indie games available.
Desura was only available for Windows but now the developers have launched a limited Beta programme. To get an invite, please join this group through Desura on Windows: http://www.desura.com/groups/desura/members
A brilliant move by Desura and a huge boost for Linux gaming community. I know whom I am giving money next time when I am buying a game. Valve, are you listening?
