MicrobeWorld

Bacillus is a video game named after the organism the developer studied in college. It's very different from other video games in that it features an accurate model for evolution. So accurate, every bacteria in the game has it's own genome (represented by A's T's C's and G's of course). But the game isn't all scientifically accurate, the developer added some fun by going a bit further than our current knowledge of microbiology, such as adding new interactions between microbes, letting them metabolism new metals, and other added features for fun.
