A special form of battles where teams of 3-4 people fight each other. Well-elected team members can be valuable members of the war machine. Instead of wasting too much time, everyone performs a task (space exploration, tank development, buildings) in some kind of guild system. It is good in terms of effectiveness, but inventions need to be shared quickly in diplomacy.
Traders should not be expected here either. It is appropriate for a multi-income empire to support the poorer with money. Here it is enough to think about 10 thousand money a month. The spy network alone is in question, and everyone is responsible for resolving it. Exploration, on the other hand, is carried out by stronger empires.
