Suggestion for My Land:
Crops could have genetically modified versions, such as:
Faster Growth: Grows Faster
Bigger Crop: Harvest worth more. If you take my machines suggestion it would instead give more units of crop.
Internal Pesticide: Immune to birds, but worth slightly less. If machines suggestion, it would instead give less units of crop.
Spreading: Spreads to nearby empty land. When spreading, small chance to gain or loose a genetic modification trait.
Beauty: Adds to land attraction value.
Animals Could also be genetically modified(would be passed on by breeding, small chance to gain or loose a trait):
Improved Metabolism: Requires Less Food to grow
Fattening: Higher max Value
Improved Breeding: Breed faster, but babies worth less when born.
Cuteness: Adds to land attraction value
It would be super duper cool if these could be mixed and matched in a settings menu. Each one would add an additional cost, and could maybe require researching(genetic lab building??)
