A realistic, but fun, ant simulator, where your progression through the game is narrated by a documentary filmmaker and scientists. Battle spiders, take down a ladybug, evolve a colony of amazing ants.
Difficulty: Gets tricky, but teaches new things incrementally.
Content: A lot of very accurate information about ants, from pheromones to their predators.
Release: Currently in Early Access. (If you buy it now, you’ll be able to access a few hours of content, and more is intended to be be patched in later.)
Age-related suggestions: This would likely be more enjoyable for patient kids aged at least ten, just because of its complexity.
Consider consulting detailed reviews before purchase.
