News translated from holarse:
It is really going to happen. Valve started the beta phase of the steam linux client. From 60000 applications they chose a number of users and gave them access to the steam-client running on Ubuntu 12.04. They plan to add other distributions and to add more users to the beta-phase.
The first game running on the linux-beta is Team Fortress 2.
Valve will announce further news on this link.
I hope that this will be the beginning of the breakthrough of linuX as gaming platform. We all knew that linuX is totally suited for online gaming – now the masses will hopefully realize this as well.
