Who goes first in On Mars?

Eagle-Gryphon English Preview rulebook, ©2019

On Mars game cover, Eagle-Gryphon Games edition

The player with the most viewings of The Martian chooses a turn-order space first. After everyone chooses, the lowest occupied numbered space takes the first Colonization turn.

Rule details

Turn-order spaces are chosen clockwise from that initial chooser. The first chooser is not necessarily first to take a Colonization action.

The First Colonists variant assigns spaces using randomly dealt tiles instead of letting players choose their spaces.

Solo setup assigns Lacerda’s space with a random First Colonists tile, then lets you choose your own space or randomize it.
