Ran across this odd breeding game: Breeder. It took me a bit to realize there’s a goal state that one’s trying to reach, but that makes choices more than just aesthetic.
They’ve got other stuff. And, it’s part of an 8 week long series:
“Routes is an eight week game from Channel 4 Education in association with the Wellcome Trust. Routes is live from January 26th through to March 26th, and during that time players will be invited into a world of genetics, evolution and the human genome.”
