I have to agree and say that split screen is classically bad ass. It seems that all the talk is for when a friend comes over though..
Is there a way to make split screen in an online four person server? Basically just spectating the other three players but, it totally recreates the vibe of the multiplayer. I feel like some people may say that that's cheap but that use to be the only way you could play multiplayer!
I think it's worth looking into. You don't have to worry about multiple joysticks and whatnot. And gameplay would be a lot like the original. Playing with no radar, on the classic maps, seeing who can navigate a map better and sneak up behind someone... yeeeaaaaaahhhhhhh.
