Hello. I have some questions about when you create a custom race..

1. The warrior trait. As far as my understanding goes all this does is when you create your starships the crew on your starships are already at the adept experience level, which provides combat bonuses and making no need to create fleet academies orbitals at your planets, (they are disabled if you pick this ability). Is this correct? Is there any other hidden bonuses to this ability?

2. Also to my understanding there are planets with 4 types of atmospheres. If you pick all 4 types when you create a custom race it takes 3 points.. However there is a ability called... anaerobic ? not sure if that's how its spelled, that does the exact same thing according to its description but instead it takes 5 points to pick.. So, my question is am I missing something here? Why would I pick 5 points over 3 if it does the exact same thing? Is there some kind of hidden bonus or something?

Thank you for your time.

1) Yep, spot on for the first one, it puts your crews at rank 3, rather than rank 1 when they are created. Fleet Academies only train up to rank 3, so it means you don't need those (and they are disabled)

2) You're kinda right, but Anaerobic gives more green worlds than selecting all atmosphere types. If you've got Subterranean and Anaerobic, pretty much every world will be green to you as your people can live anywhere.
