Afterwork Session - Terraforming Mars with Prelude and Hellas/Elysium maps

Join me in playing Terraforming Mars with Prelude and alternative maps, a game in which each player has a corporation and we all use our cards (projects) to advance the terraforming of the planet through raising the temperature, the oxygen level, and the ocean coverage until the environment is habitable. The one who has contributed the most and collected the most victory points is the winner.
When the three global parameters (temperature, oxygen, ocean) have all reached their goal, the terraforming is complete, and the game ends after that generation. Count your Terraform Rating and other VPs to determine the winning corporation!

We play with Prelude, Colonies and various promos. Probably Hellas or Elysium maps. As I have not hosted it with Colonies before, I put an earlier start and a bit longer playing time. (Picture above is from a game with Venus, not with Colonies).
