As a Roblox developer, I’ve known for a long time that some games work well with the cross-platform enabled. But oftentimes games in the FPS genre are forced to have separate games for PC players and Xbox players just to even out the playing field. Another issue is updating the game, you’ll have to go between games making sure everything works correctly. Something like this can lead to the console version falling behind in updates and just generally becoming broken overtime.
Here’s an example: Let’s say you have Phantom Forces a rather popular game that has a lot of PC/Console players and instead of relying on two separate games for either platform. There are servers that only console players can join and servers that only PC players can join. Basically taking one game and allowing people to go to one place for that game. Updates will be easier to work on and can allow developers to not worry about another version sitting in their profile or group.
If this issue is addressed, it would improve the development experience for tons of developers working on games that require highly reactive hand-eye coordination and intense gameplay. This can help smooth out the development of tons of existing and up-and-coming games.
