In Planet Coaster, you gain different career ranks by how many stars you collect in career mode. I believe I got to rank 3 after completing 3 scenarios.The number of stars you need to get to be rank 3 is seven.
The 2 first tutorial scenarios are pretty easy so I won’t be giving a guide for those. However, if you do want a guide on those, please tell me.
The next scenario I did was the “Pirate Battle” one. If you just want to get to rank 3, you only need one star in this. However, I recommend getting 3 stars as you get 2 other 5g achievements.
I placed down all the rides available (opening them up after obviously), spammed some scenery by them and then sped up the game (by holding
a couple of times).
