Watch “How to Play Earth's Solo Mode with Playthrough,” a how-to-play guide for Earth from Merlin's Manor on BoardGameVideo.
Description provided by Merlin's Manor on YouTube:
In this video, I teach how to play the solo mode of Earth. I start out by going over the sics and then jump into playing the game to teach in more detail along the way. I played the game on Medium difficulty, but I briefly go over what the other difficulties entail.
*Note: Whenever Gaia scores an objective, you can choose which one she receives even when you have taken the 1st place on one and the first place is available on the other (in other words giving Gaia 2nd place under you instead of giving her 1st place on the other objective). The wording in the rulebook may make it seem like you must choose the higher value of the two if Gaia has not scored either yet. However, what the rulebook is saying here is that you must give her the highest position available of VP on that objective... i.e. you cannot give her 2nd place on that Fauna card when 1st is available. The designer of the game has confirmed this to be the case.
