My dream is a lot more narrow: I want a mod or an official game mode for Deep Rock Galactic where two teams of 4 dwarves race to the center of a cave for resources and have to take it back to the drop pod. It should disincentivize players from fighting each other directly, but instead deploy traps and waves of bugs against each other.

It's SUCH a good game as it is. I think it could only improve with the addition of creative PvP modes.
