1) And how do you start with this Castle?
2) A "logical" player? Does that mean logic is measured by the amount of resources and money?
3) Playing for a long time and having a lot of money... that's rare. But if you don't play for long and capture this Castle, is that it? The end?
2 - The more logically you use resources, the more you have.
3 - Playing for a long time is a matter of preference; capturing it quickly doesn't mean you'll be able to buy everyone there! So, the balance is taken into account.
Sorry, I didn't clarify:
A Castle with only high-level creatures - you shouldn't START with it! This intermediate Castle is placed somewhere on the map between players or far from them - only the most experienced player will take it, and the game will develop accordingly.
That's what I wanted to say.
