I would love to see a game that needs cooperation between x agents to wins.
I feel like play as a team in a imperfect information environnement is one of the most interesting AI challenge out there.
Imagine a 2d csgo with no need of manual skill, no aim or reflex, just player placement, crosshair(view) placement and teamplay.
If you know some game like this let me know please, if there is not i will build it one day.
