You start off as this insignificant bit of bacteria and you grow and evolve through advantageous mutation […] You go from being bacteria to a galactic god.
On the face of it, this is raddest ever, but then again, the problem with these sim games is the sometimes spurious assumptions made in the algorithms. Well, I guess by “problem” I mean “dissimilarity to actual bacteria → galactic god evolutionary processes,” which is probably okay. So never mind, raddest ever.
