Steam – Non Steam game on another computer

Having everything in one launcher is nice, but the big advantage is that it will try to enable the steam in-game interface. This isn't always a good thing - you may want to disable it for some games if it makes them unstable.

Launching non-steam games from steam will also display to your friends that you are playing that game. For me, this is a critical feature. It will not track your play time on that game, however.

Update: You can now in-home stream non-steam games if you add them. Thanks to the other replies for mentioning this.

Yes, you can do this. After playing the Steam-installed version of Frozen Synapse (so that you have a registered account and email address), you can go to Mode7's website and use the form there to request a link to download and install a copy of Frozen Synapse independently of Steam.

Note also that the Steam-installed copy can be run without going through Steam. Just browse into the install directory and run the exe directly. (Don't use the desktop icon created by Steam, as that runs it via a steam:// URL instead of starting the exe directly.)

I have personally used both of these methods, having initially installed FS on my dual-boot laptop via Steam, set up an icon to run it in Windows 7 without starting Steam, and also run it under Ubuntu without Steam even being installed. I then requested a download link from Mode7, used it to download the OS X version, and installed that on my MacBook Pro to run without Steam.
