The Steam platform is the largest digital distribution platform for PC gaming, estimated in 2013 to have 75% of the market space.
In 2015, users purchasing titles through Steam or through Steam keys from third-party vendors totaled roughly .5 billion, representing 15% of the global PC game sales for the year, based on estimations made by the tracking website Steam Spy.
I was actually planning on writing a tutorial on how to install the Windows version of Steam on Mac OS X with a standard Wine installation.
Then I discovered that this method was actually easier and it keeps everything self contained within an file.
If you are new to Wine I think you will find it very user friendly and if you are already familiar with Wine, I think you will find that it has enough advanced features to your satisfaction. This is so awesome because I have found that some Windows applications only work with certain versions of Wine.
Update 3-20-2014: It looks like the “No Config Server” error has been resolved.
Running a test install, I was able to successfully go through original tutorial steps without any errors.
At the time, Steam's primary function was streamlining the patch process common in online computer games.
Steam was an optional component for all other games.
