Hello.
Is there a way to tune down unit supply or increase unit maintenance, any submod or extra setup.
Every game is turning into grind fest of 30-60 for each civilization and it's extremly tiring and repetitive to keep track of every unit during wars or when upgrades are in order.
@balparmak has a modmod for this.
Is there a limit to the number of research agreements, similar to the limit of defensive pacts?
No.
