The most challenging maps for you.

Let's not forget that the AI doesn't follow the rules... if it's smart enough, it will use a diplomacy mod to form a powerful alliance, arrive in the second or third week, and crush you... or it will use a mage with blue sprites to overwhelm you... so be careful what you wish for!) no one thinks about the negative consequences!)
P.S. I won't even mention author-made maps, because the AI won't give you a chance there.

P.P.S. I'm not even talking about how long its turn takes, because the AI shouldn't take that long, since there's quick combat...
