ELI5: Why cant most console video games support cross platform multiplayer?
gpt
They actually can, but is there any point in doing so? It's not going to increase sales. If anything, as it is, some people might buy the same game twice because they want to play with their friends on both PS4 and XB1. 

The problem with making it cross console/PC is that PC will always be superior in terms of control - we have a keyboard and a mouse, whereas console shooters have to mess around with a controller, and often have autoaim to compensate. That just creates too many balance problems to be worth it.
