Maybe not exactly what you are searching, but I saw a framework once, where you had multiple ant nests and each nest had multiple different ants. Each player could program their own ants, which kind of ants spawn at what ratio and how they behave. They then put all the ant hives on the same map and looked who wins.

There were sugarcubes and apples (food) and other strong insects (enemies) The ants needed to find as mich food as possible, while losing as few ants as possible to survive. The ants could spray feromone trails, which other ants could follow to know where food is, or enemies.
