“Best map for Heroes of Might and Magic III” (2007).

Unfortunately, only one map from one participant can participate in the contest!

Something doesn't quite add up... hmm.

In post 30, you, esteemed VDV_forever, said the opposite.
To the question:

Can we submit several maps, for example, two or three, or only one, from one participant?

You gave the answer:

Yes, you can;)
Sincerely, VDV_forever

P.S. I believe that contestants should be allowed to submit several maps. And the more maps a contestant submits, the greater their chances of winning.

The latest version of my contest map Heroes World with a description.

Your description deserves praise. Your description can be used as an example for other participants in the contest.
