Some suggestions: Split screen, tables etc.
Hi, I really hate to play on split screen, but in some ocasions is completely compulsory. Maybe Parsec could do something about it. My suggestion is this, select screen regions and assign it to a certain players. Could be in the client (With a permisión or something like that) or on the hoster side.
I made in photoshop something quick for you to get the idea.
The idea is that anyone can play with only one screen irregardless of split screen. Could be activated with a hotkey for some control. Like being in the menus and watch fullscreen again.
