Tips and Tricks Edit
- Note that if you place a Monolith on a creature planet, it will raise the creature all the way to space and count towards your Brain Surgeon badges. It however will not count toward this achievement, which requires you to evolve existing races that are already on tribal stage.
- This total of 20 civilizations can be across a number of games, and the achievement is awarded on the placement of the 20th monolith (it is not necessary to wait for the tribe to be raised to the space stage).
