Permaculture video game thoughts

I recently saw that there is a farming game out there but is completely conventional farm orientated not so permie. I wish there was a permaculture video game. An experience which focused on being creative and building life not poisons, guns or cars.

Some games currently use building blocks to a great permie game.

-custom terrain creation (Mine craft, though it is to blocky for my liking)
-virtual animals (Buck hunter)
-maturing plant life (Tropico)
-day and night, weather and seasonal changes (Harvest moon)
-home design (The Sims)
-forest management (Stronghold)

any feedback, thanks.

Dan, you may want to look at this thread.

I am not sure this is a good idea, but there are different opinions.

Thanks I will.
