Valve is not publicly traded. They do not have to answer to share holders. Their service offers free weekends on games they publish, and ones they don't. There are weekly sales, and you can download the games on any computers you own by signing in to your Steam account. In summary, Valve is better than Jesus and maybe even Thor. I'm not sure who my favorite deity is. Cthulhu is pretty rad.
+1 After I read his post I was going to say that. Valve is the anti company, they shoot for profits but the customer comes first. They are holy IMO.
