Computer games

The first idea for a computer game or simulation is a "God" game. Its like a cross between Populace and Sim City, except that you are designing a running and functioning permacultured food forest or "farm". You have a set piece of land with its own gradients and features (water supply, original biomass, climate etc). The idea is to establish plants (with information on growing condition, effects on other lifeforms water and soil, companions, uses, annual or perennial), people, insects, animals so that the become a self sustaining ecosystem that runs itself. Problems that would come up such as inappropriate plants wouldn't establish, disease outbreaks in wet periods (and Eco solutions), population explosions of animals when food supply takes off. It could have a lot of detail, such as companion planting, being able to move the soil around, the state of the soil (clay, sand, loam), rainfall, climate (temperate, tropical), fungus (useful or destructive), "weeds" etc. You could buy stuff from the nursery with money made from the produce.
There could be an easy level (simple with a good piece of land), a moderate and a hard level. It would be good to have a feature where you can set your own piece of land so that people who already have land or are thinking of getting some can work out how to establish the ecology roughly without the painful real time/space/expense process of trial and error.

The idea for the second game or simulation is another "God" game. In this game, you get to run an natural ecosystem. In it you have plants, animals, insects, fungi, bacteria. There is herbivore prey (small and large) and omnivores and carnivores (hunters and scavengers), of which you have to maintain the right balance. There are natural features such as climate, geography, water supply.
It would be a great interactive way to educate youth on the environment, and quite satisfying to play (as an adult). It would be great also to have a feature that you can be one of the creatures at will. So if things are going well, you can roam the grasslands as one of the lions or rabbits. It would also be interesting to try and incorporate humans into that ecology, to see what effect they have at varying levels of development. That would be a great way to educate, and make the game more fun.

They are both massive projects which would need a lot of patient research and design, but it would be well worth the time and energy because it would change lives for the better.
