Answer: I like all of the random things that Players attempt to have a Binary or Creature do. It's a large portion of the reason that I fell in love with Tam Lin's B16nary Original and I decided to start Binary R3coded and B22nary. Though I do feel like I should mention that it's not impossible for you guys to take advantage of things outside of the setting. It hasn't happened in either of my Binary Games, but in Tam Lin's B16nary Original, someone did manage to pull a missing threadmark into the game and turn it into a weapon.
One of the things that has stuck in my mind the most in relation to B22nary would have to be the Fire Trees or Frees. They can be a bit of a pain to keep a track of because of how they spread, and after a certain point they make it so that Druidry doesn't really work inside of them. It's why I'm glad that three factions are placed right next to the Undead Forest, keeping the Fire Trees within it from spreading further east and south.
A funny thing would be how you guys seem to have forgotten that the Nature Princess has an Adaptation that can be used to create a new Frog species. She's been right there for a long time and yet... no one has tried to convince her to lay an Egg. Or try to develop a Frog into another Creature.
