What exactly is banned by the 10 Réunion Island Crisis treaty? Use ground forces on Earth? Using ICBMs on Earth? Any kind of international war?
Land war on Earth. ICBMs and space born attacks are still allowed. So JUST ground forces, on earth.
I did that as one of my few admin "This is how it will be" as a early ground war is one of the most boring ways to play this game. Much prefer to have fights over Europa myself.
As a note - a team can propose to expand the Réunion treaty to include other things. Though the FSA will not consent to never flinging nukes.
