There's no need to flip a coin – there's a better option!
So, let's say Vasya and Petya are playing. They need to at least start the game. And at some point, they decide they can't finish the game for some valid reason. They save the game and contact the judge. The judge loads the save and looks at the thieves' guild information. Whoever is listed first in the "kingdom army strength" field wins!
By the way, in all the years you've been playing "Heroes," have you ever seen a tie in the thieves' guild? I haven't!
I understand that some people will strongly oppose this option, but my job is to offer it.
