>Is it about servers?
yes
>Do all consoles have the ability to support cross-play
theoretically, yes. if they support online play, then they could update the console with new, cross-play servers. the game itself, might or might not need an update from the maker.
>and its just a matter of the developers working to include it in a game?
no – the pc version of the game has servers controlled by the game maker or the players. console servers are controlled by the maker of the console. both parties would have to work together to combine servers or get the existing servers to cross talk.
>What are the challenges involved in cross-play?
mostly the cooperation thing, but in a lot of cases, like first person shooters or games that need quick move and click responses, consoles with controllers are at a distinct disadvantage to mouse and keyboard, so cross play with pc isn’t really a good deal for them anyway.
