It's a pity that many people didn't like this part, and because of this, you have to replay maps that you already know by heart instead of looking for new ones.
Regarding the fact that
S - M size maps can be completed in a couple of hours, even if you fully explore them and clear them of all neutral creatures.
Large maps: 106
Isn't that enough to play?
And this:
many of them are in a language I don't understand.
I've already searched many sites, including this one, and downloaded all the works that I liked. Sometimes I still look for new maps, but rarely find something that is really worth playing.
PS Have you checked Heroesportal?
