I prefer Planet Creation, and I'd use it to create entire planets suitable for lifes, and as well create some species.

Or also I'd just create planets for fun (like create a Vacation Paradise Planet XD)

Technically if you were going to give it species or a race you would need entity creation

@Danya51 I mean that through planet creation, you could manipulate the life and nature of it as well, so you could create species, etc.

I just looked at it your correct

I'll create a planet where dragons exist.
