Unless I am mistaken (if I am my apologies OP), I think he is asking for "split screen" play where two people can sit on the couch and play side by side on a single screen, like how console games tend to do it.
That's a really weird expectation. I can't think of a single PC game that allowed you to split screen on one PC... I mean there is hotseat for people who want to share one computer but... O.o
