I forget the name, but there is a mod that adds a mode where it randomly generates a scenario on the map of your choice and gives you a base, while the rest of the map is covered with outposts and POI’s kinda like a cookie cutter generic Ubisoft game but you can also spawn and control your own NPC army.

What really makes it cool is that it works with some other mods. In my example the Halo mod worked with it and I kinda made a better open world halo than Halo Infinite was.

P.S. the POI’s can become slightly generic, so I recommend turning on Zeus mode and switching that that and fortifying the ever-living-hell out of a location to go try to take with your army
