The gaming service StreamMyGame does exactly what its name suggests and lets you stream games stored on one computer to another.
Cleverly, it will also let you play a Windows- only game on a Linux system. You just need to install the Server software on the Windows PC, and the Linux Player on the other one.
The free version of StreamMyGame (with adverts) limits you to playing at a maximum resolution of 640×480 pixels, but you can upgrade to a premium account for $9.99 (about £6.17) per year.
So, go ahead install linux, a virus free operating system and play your favorite games which were not there before.
