Arise thread! I renamed the thread since it is more general biotech than genetic engineering.
But the reason I am reviving it is to ask a question- how many DMs use domesticated animals that have been magically altered? With all the spellflingers about, one would expect some improvements for both the nobility (falcons, dogs, etc.) and the peasants (livestock). How about plants? Since they are so much easier to propagate than animals (seeds, cuttings, etc.), they have that much more potential to change a world.
How about weaponized plants and animals? A grass that produces toxic pollen could be devastating to farms and boars that can digest cellulose could be a way to drive off elves (via eating everything green).
