8. Keyboard and Mouse

Pros: The PC isn’t a console per se and we hate to encourage PC elitists – but the WASD x mouse combo still reigns supreme for shooters, RTSes, and MMOs. Not so much for Kinectimals, though. Which is probably another pro.
Cons: By using a keyboard and mouse, you share a significant commonality with the guy who scoffs at Crysis on a console as he pushes his glasses back up his nose.
