That's a bloody huge milestone. We all know quality over quantity, but with 1000+ games now on Steam for Linux, there has to be something for everyone!
The current count for me is at 1002, I imagine it may be a few lower in specific regions due to region blocking, but with more releases planned it's only going to keep growing.
I still remember the days of being in absolute denial that Steam would come to Linux, and now we have masses of games, some little and some big. We have Steam Machines with the Linux based SteamOS coming our way, and tons more big games to come.
Here's a pointless screenshot for you:
What a time to be a Linux Gamer.
Now, where's my rum gone? More on this breaking new story when I find my rum to celebrate.
