PC gaming is famously a muddled, complicated affair. If your only experience of videogames is via consoles, then common PC obstacles like system specifications, graphics drivers, port forwarding and DirectX are going to scare and confuse you.
But Microsoft is here to help.
In May 2007, shortly after the launch of Windows Vista and with Xbox 360 increasing steadily in popularity, the company launched Games for Windows Live. Part of a larger initiative that includes branding of all PC game boxes and a rating system to simply identify which games your computer is capable of running, it's an application and service that offers online matchmaking, auto-downloading of patches, a downloadable content marketplace and, in some cases, crossplatform play with Xbox 360 users.
