While Microsoft is actively encouraging cross-platform online play, Sony is actively avoiding it.
This all stems from a couple of pretty big E3 2017 announcements by Microsoft and Nintendo. Minecraft, one of the biggest and most widely available games on the planet, is going cross-platform, finally unifying all the individual versions in one glorious block. Xbox, PC, mobile, Nintendo Switch, all will be able to play along together as one big happy family.
Rocket League developer, Psyonix, also announced Rocket League for Nintendo Switch. A great announcement on its own for Nintendo fans, but made even more exciting by the news that version will join the current Xbox One-PC cross-platform play family.
The notable absentee in both cases is Sony. It's not as if it can't be done, because it can. But why isn't it happening? Sony's 'defense' of the subject is pretty questionable.
