I had a thought for some time and I think Xbox is now in a position where it would be possible for them to do something alike.
Let's say you make 2 game an RTS and a FPS in the same universe like Halo wars and infinite, but those game are game in their own right but what if they can be combined for ESports. Like your team will consist of a mastermind setting objectives issuing orders and producing assets playing in the RTS settings and a teams which will resolve orders by fighting FPS matches against the other teams.
The map available in the RTS view would be a collection of smaller maps in which instance of FPS matches can be fought independently of each others.
The FPS matches would likely be unbalanced due to diverging objectives between both team mastermind so player skills could shine. Like a masterminds may sends a single spartan in a sections with a scorpion and the objective to hold the section and simply preventing the other team from capturing it while sending the brunt of their teams capture other section in hopes to create a way to reach enemies base. The assets production would give players different starting equipment, vehicles, varying amount of re-spawn, varying amount of supporting AIs etc...
This will give a kind of dedicated E-sport way of playing and a more player oriented new look of a meta-verse settings. and this idea may be expanded upon to include even more diverse sets of interconnected games which can all be games in their own right while also be played in a MMO style with other games. Like a space colony game which have players producing goods for profits while a space exploration games need to buy those outputs for exploration trips and uncovering diverse settings ripe to create a space colony which could then be auction to player of the first game.
