Journey

Besides this author, there are many other wonderful maps on the resource. You definitely won't be bored ;)

That's for sure - after playing through all the official versions of Heroes 5 - the classic, Lords of the North, and the Horde - I started playing additional maps that came with the game, and when those ran out, I started getting maps from the generator, but they turned out to be uninteresting.
Making maps myself (as I did in Heroes 4 and 3 or in Starcraft) turned out to be a much more troublesome task than before and requires time (which is always lacking), and the editor didn't appear right away.
In my search for new maps, I stumbled upon this wonderful portal, and for over three years now, I haven't had any problems finding new and interesting maps, and I am very grateful to their creators.

By the way, (at the end of the fifth month) I just took the Dwarven Outpost - it happened rather boringly and uninterestingly - the beginning was fun, but the endgame turned into a chase around the stone - my hunters were running away from the hybrid of a rat and a chicken until the hero killed this monster.
