I was considering "borrowing" a copy (installation) from a friend. After playing with the creature editor demo, looking at some gameplay footage, and reading some in-depth reviews, I came to the conclusion that the game is a sandbox in cosmetic design only. There is no diversity at all, which is what I thought the game would be all about.
When I first saw it, I thought it would be akin to Sim Life (A very awesome game) where the models were created procedurally, but also actually meant something. However, it's just skeleton manipulation with soft meshes, pre-scripted location actions, and little (if any) diversity on a physical scale. The ruleset is static, and each creature is identical with every other on a practical view.
Very disappointing. Not even worth the HDD space.
