Here are some tips and tricks to achieving greatness in New World:
Plan ahead for which types of higher tiered creatures you want where.
Create the appropriate landscape and trees early.
Max damage shotgun is a great, cheap weapon.
Upgrade resistance early. The longer they can survive, the better off you'll be.
Don't over-upgrade to the next tier too early. Fully upgrade evolve for the ones you have.
Getting lots of eggs ready to hatch at once can get you over the hump to meeting a hard objective.
Running speed is the 2nd most important upgrade.
