solved it by setting permissions manual:
chmod -R 755 '/home/dan/.local/share/Steam/steamapps/common/Counter-Strike Global Offensive/csgo_linux'
OP:
Hey guys,
So I wanted to try out CSGO on Linux, using Fedora 23 on my 2013 (Haswell, i5-4250, HD 5000) Macbook Air.
Unfortunately my game wont start after I downloaded it with steam.
I downloaded it and clicked 'Play' but it wont even install (like it should do?)
it will just open this small window (Launching CSGO) and after that disappears again, nothing happens.
Anyone having an idea how to fix this?
