A One Paper Game about making the prettiest and most balanced ecosystem. You print out the paper and play by writing on it with a pen(cil).
For example,
- There must be twice as much prey a predators.
- There must be twice as many plants as prey.
Could also be more like a logic puzzle by having some Sudoku-like extra rules and special effects of animals (“only eats animal X”, “counts for 2 predators if Y”). This would dictate how exactly to fill up the map, instead of allowing randomness / creative freedom.
IDEA: Something about invasive grasses, or species, or just the threat of humans. And you have to prevent that?
