Yes, I indeed have that in mind as per Ben’s post 
. However, they clearly have some sort of means of making creatures, as is evidenced by our new little goat deer thing friend 
. Putting at least a taste of this tech in the hands of the player base could be a nice way for a 22 person team to turn into a 5,000 person team, at least when it comes to design. The tech and details are for the devs to worry about. I’m simply providing the idea in response to Ben’s original question. 
Something as thorough as Spore’s creature generator would be difficult indeed to make and, as I pointed out, would take a considerable amount of time. But the idea of something like Spore’s creature generator is worth exploring, or at least mentioning, I believe.
