Well, its not stickied and i searched and didn't find anything so I decided to make an official steam thread we can talk about all thing related to stem, I plan on making an LPA steam group, and we can create events sometimes and you can post your steamID to join with other people from this website. Join this group: http://steamcommunity.com/groups/linkinparkassociation/
This isn't related in any direct way, but: http://www.gamespot.com/news/half-life-3-wait-explained-6372687
Valve are also now officially porting Steam to Linux. I think that pretty much guarantees all Valve games will be supported on Linux also but other Third Party Devs will be hard to convince to follow. Half Life 3 on Linux? Sounds good to me. BTW. There's a photo of Left4Dead running on Ubuntu.
I do but I do not remember it as my current computer is too shit to play any game released after 2001 so I don't use it. TL;DR I forgot my steam ID because it never got used. On a side note, when I had Linux on my computer, games were actually better supported. Weird, I know. There was just one exception emulators would run horribly and I really wanted to play some old DC, PS1 and N64 games... thus Windows.
