Two questions:
1: What is your system information as requested at https://github.com/ValveSoftware/steam-for-linux#reporting-issues ?
2: What are the three games you bought? Killing Floor, Left 4 Dead 2... and what other one?
There does not appear to be enough information here to pursue this further. Closing pending feedback.
Nothing extracted yet.
I bought three games to Steam (big mistake I think).
One is killing floor (with which I have no problem).
The others are are left 4 Dead 2 for Linux. One of them took up 13GB in downloading the other just 4 (I think).
By downloading the first one (the biggest) play as well ... but to download the second two are absent. I offered to buy them ... BUT HOW PEOPLE EXPLAIN uselessly STEAM, the game I bought.
You will have a reference solution or the problem.
From already thank you very much.
