I'm designing a video game in which players command a small crew of aliens (10-20 of them) who are building an outpost on a planet. They are a bit larger than humans (around 2 meters tall) with about the same diet. They live underground in a structure sort of like an ant colony and have better technology than modern humans (including nuclear fusion and algae fuel).
What could I do/what technologies could I use to minimize the space it takes to grow enough food for this crew? I'd like to use no more than a few cubic meters per person. Is this possible?
A little more about this world:
- Players can buy shipments of food, but not very often because they are expensive.
- There are some food sources on the planet, like fruit trees. However, they must be harvested and don't produce food often.
- There can be fictional fauna/flora as long as they are realistic.
- I don't want the crew members drinking smoothies at every meal like in Wall-E. Food should be interesting.
