When it will come from the rest of the game Valve? (sorry for my english)

[Красивая Грязь]

TF2 on Linux works fine, when it will be ported to the game on the same engine? such as CS: GO Portal2 Day Of Defeat Source

[Cool Chulainn]

do a search, there are dozens of threads already about this subject

Games that you listed doesnt using same engine but different versions.
Engine that used by TF2 also used in L4D2 so...

I bet many Source games are ready or almost ready, and Valve just waiting to release everything together with Steam on Linux release.
