So, I’ve been looking up a lot of science discussions about aliens for an upcoming project (you’ll see) and it’s a bit of a rabbit hole to say the least. There are countless examples of aliens out there from Star Trek’s various foreheads to the tongue-in-cheek aliens of Futurama. But for a hard sci-fi setting like Eclipse Phase that won’t work. So how do you make some interesting but realistic alien ecosystems? Here are some resources.
