Global Parameters

Temperature goes from −30°C to +8°C in 2°C steps, oxygen from 0% to 14% in 1% steps, and oceans from 0 to 9 tiles. Each step raised gives the player who raised it +1 TR. When all three reach their maximum, the game ends at the end of that generation.

With Venus Next: Venus is a fourth track from 0% to 30% that gives TR but does not end the game.
