Vortex Wars

I would like to see a game setting that made the property's sizes throw more weight if larger (or less if small) during a roll, based on the actual physical size of the territory.

I think larger territories would make sense to be stronger in offense but weaker in defense. Just sayin'

I agree, but what if someone made a map with one HUGE territory and several other smaller ones. Then what happens?

It's not much different than say a +5% attack bonus with specific races. It does not mean you always win, or always lose. It is just an advantage. Plus, this is much less, as in your case it is just one property.... on every property like a race is.

This would cause lot of large territories and I don't want that, it would not be fun if you could see only one territory at a time
