Answer 14

I have portal 2 for the PC, installed and running just fine WITHOUT STEAM... Never had steam, I think it's garbage and will NEVER use it. And for all you computer noobs out there... there is no such thing as a game that REQUIRES a launcher, such as steam, to run. If there is an .exe, then there is a client workaround... Lets not forget to mention the private servers for online play.
