I would assume split screen may cause the game to lag and or use more pc resource? And no offense to anyone here.... Though I just don't see the point of split screen on pc... I haven't seen a game offer that in like forever. Plus most people usually have there own laptop or so on to play games. Or they just buy a console since im sure 100% of the games on there have split screens.
Don't take anything personally here, it's more aimed at the institution than anything else.
I'm an older gamer, and the way we used to play games before the internet, was sitting around the console/computer. Now some of us own PC's, and are not ashamed to either, want to plug it into a TV set, or allow others to join in on our experience, without sending them home and telling them to buy a copy of the game. I'm now more of a keen board gamer, and board games are suddenly becoming more and more popular in recent years and it's this, the lack of social interaction within video gaming, which I believe is driving the growth of board games. Parents who were gamers seeing their kids become increasingly isolated, tied to their bedrooms, phones etc, is not what many could call healthy. So here we are discussing why bringing people together, physically - for a social activity, is something that we should cling on to. I miss the time when split-screen gaming was something wanted, regardless of the (slight) drop in fidelity or performance.
These are sad times indeed.
Add Note: Split Screen is almost synonymous with Halo.
