SimAnt

https://archive.org/details/msdos_SimAnt_-_The_Electronic_Ant_Colony_1991

Maxis’ third Sim game. A nostalgic treasure. Take control of a colony of ants. Survive environmental challenges, eventually wage war in the kitchen.

Genre: Simulation.
Platforms: Web.
Difficulty: Gets tricky, but teaches new things incrementally.
Content: Lots of ants doing real ant stuff. Try Experimental Mode, too.
Release: This is a super old game. It’s free to play but very dated. Mostly for nostalgic parents who played this at a friend’s house in 1991.
Age-related suggestions: I think I played this when I was in early high school. Ant interested young people are more likely to enjoy this.

Consider consulting detailed reviews before purchase. (But you can play it free in your browser, so why not?)
