Walkthroughs for custom maps.

I'm just curious about how different communities approach completing maps, even in Chinese or European ones.

Yes, it's interesting to look at from that perspective. As far as I understand, Chinese playthroughs don't shy away from much (although I haven't seen them using the Admiral's Hat bug or dismissing/redeeming a hero on the same day). For example, in the Metataks playthrough I shared, the hero Mr. Fat is used quite actively, even though, according to the author's idea, he shouldn't appear in the tavern after Le Strada loses. Yes, he doesn't move, and his spells aren't relearned, but he redeems Mr. Vertigo from the tavern several times, which leads to rather peculiar consequences.

But there's a very fine line here: what is a bug, and what is a feature? For example, is the AI's reaction to a Wall of Fire, or tactics involving keeping AI troops within the city walls (blocking the gates, using summoned elementals, or exploiting the strength of the AI archers), a bug or a feature? In my opinion, the Berserk "bug" should be considered in the same context as the examples listed; it's more of a feature that requires knowledge and skillful application. However, the "bugs" of Earthquake, Clone, and Sacrifice are different. Although, it's unlikely that there can be any universal view on these things.
