The de facto standard home computer since the mid-nineties, the IBM PC Compatible as it used to be known, is at the cutting edge of games technology. Due to its constantly upgradable architecture, game consumers don’t have to wait for a new console to get the latest technology, they just by a new part. The standard PC interface of keyboard and mouse effectively give it an analogue games controller with 105+ freely configurable buttons, this has proved popular for more complicated simulator and FPS games but the fact that it demands a desk prevents casual living room and group play. I’ve just realised that this is a rather cold and soulless description but although it was quite accidental, it is entirely appropriate. What is undeniable is that the PC is the most popular gaming platform in the world.
