Round table

The first one is good, but the second one has too many castles. I'm testing my own template now, and it's really cool and interesting. It's good to have three castles when the heroes are stationed in the garrisons. Yes, having only 8 heroes for 3 castles is a bit too few... But having only 2 starting castles is also too few, in my opinion.

I just noticed that the first template also has 4 starting castles. No, having only 2 heroes per city is really too few. Maybe you could make it a hyperpyramid instead of a hypercube?
