George,
it would be a disappointment for you to go.

I really hope you reconsider,
there is room for everyone,
and all ideas,
so please stay. Wars can still be hosted on this map.

I will host wars with others too,
and there are many people who want to war with each-other.
As for people creating natural barriers around their Kingdoms,
that would have been fairly common.
What better land to have then the land that naturally protects you.
After all, most nations
would not have gone to a flat field, drawn a line and said, "That's you land, this is mine."

They would have had to fight for it,
and use the natural terrain to their advantage.
