Rocket League is a great game that already supports cross play between PC and PS4. windows 10 and Xbox one are supposed to have cross play games already, but they don't. The game is already out, and it doesn't make sense to hold the xbox back by isolating it from the rest of the community. The title isn't an exclusive title so console sales will be virtually un-affected. This move to keep the Xbox community isolated seems to be arbitrary and should be changed.
