Some people were interested in know about smart phone gaming. At the moment smartphones can join PC players on Minecraft: Pocket Edition (Smartphone app) - Minecraft: Windows10 edition(PC),
Smartphone gaming is still improving, like XBOX and PS4 decided to do remote play on them a long time ago near there launch.
Back to the topic...
Right now (at the release date of this article) the games that were suggested to be Cross-Compatible are "Rocket League", "Minecraft".
REMEMBER: Do not worry about anything. There are much more games which are going to be released which are going to be Cross-Compatible across a wide variety of gaming systems.
Unfortunatly PS4 will not be involved in this whole Cross-Compatibility thing. This is quite sad because there are much more players who play PS4 than XBOX ONE which would of meant that there would have been a whole massive Cross-Compatible community and a lot more events would have happened.
For now,us gamers are going to have to sit down and relax for a while for more updates on this whole thing thats going on in the gaming community.
