Perhaps someone can recommend maps (preferably large ones) that can be completed with a single hero or a hero with a minimal army, or even just a monster?

As far as I know, there are maps of this type, and I liked them much more than the others in all the games. If anyone knows, please recommend some.

P.S. I only know about the existence of a very interesting map from a gameplay perspective, where you have to play as a fairy dragon (and it takes quite a while)... But I don't have that one either, because I installed the game on a new computer quite recently.
