I totally surprised that no this topic yet. I purchase my copy of SotC recently and really inspired about "Create a Unique Species" part. So lets share are most excited result, that provide more gameplay/mechanical or roleplay/narrative expirience.
I am start with recreated are popular meme about...
I think it sample provide both narrative fountain of experience and provide still effective mechanically gameplay. They able to transform from humanoid size figure to swarm of 3 small creature. Represent both ability to have 3 pair of hand and very cowardly nature that able to force retreat. They still fragile but have are option to survive more that one enemy hit. And 80 exp still provide option to create 4/3/2/2/2/1 or 3/3/3/2/2/2 stats or high talent pyramid at start.
Hope see some samples from you friens!
