Best settings for nasty wildlife?

[Vegan]

Hi, i have somehow managed to get 70 meters tall beasts in one game, i usually play on max size old worlds,

i am wondering is there are optimal settings for the nastiest hostile wildlife, temperature, gravity, rainfall etc?

Thanks.

Take a medusa world and have the alien life history class enabled. That will create huge monsters.
Also set the difficulty of the game higher, that will give them more and stronger abilities.

And you want old worlds where evolution had time to produce these beasts. Like 5 Billion+.

Sure but i mean beyond the obvious, are there more subtle settings that affect that?

High oxygen concentration of 33-35& during the Carboniferous time period on earth led to giant insect fauna.

So maybe aim for high oxygen concentrations?

Signficant rainfall across as much of the planet as possible. That's going to drive lots of plants, which will both raise the oxygen level and give all these huge critters something to eat so that there are as many of them as possible.
