>My wishlist for a proper civ successor is a game that takes you from a single village to a globe-spanning superpower, not on a single map with a single handful of opponents, but starting as a village with village-sized opponents which you will conquer or co-opt, expanding the scope of the game, the map and creating new opponents matched to your progress as you progress through the eras.

In principle this could be achieved through the agar.io approach. Spawn the map with 100s of small fish. Small fish either swallow or get swallowed, and increasingly over time, you get fewer and fewer, bigger and bigger fish.
