As of January 1, 2021, non-Classic games will feature a mechanism to increase the value of Homeworlds. The loss of a race's Homeworld results in a major reduction in Happiness Score. On each planet belonging to that empire, colonist Happiness will drop 70 points, and native Happiness will fall by 20 (may be changed in custom games). If a homeworld is captured, this effect can easily drive every planet into civil war.
This penalty is only applied when original Homeworlds are lost, and occurs only once per Homeworld. Because of this limitation, there is no penalty for loss of conquered Homeworlds or for loss of a players original Homeworld if it has been retaken.
This change has no impact on the Horwasp.
