These are some serious monsters!!! It's hard to manage with just 4, and one minute per turn is barely enough.
No, I played Heroes 3. One minute was enough to move 8 heroes and build in the castle... but there was no time to think, and it was tough.
One minute is a benchmark for fast gameplay, and it also shows the player's skill level...
This doesn't show the player's skill level at all. It's more like a sprint, but Heroes is a strategy game that requires some thought and planning. I agree that in a team game, you can't set a long turn time because it would make it difficult to run a tournament, and that's why I agree with Moriarty that at least 2 minutes are needed to somehow manage. Most of the time is spent in battles, so if it's 2 minutes, it won't significantly increase the total game time.
Playing at 160% doesn't question your professionalism as a player)), but it does reduce the overall game time (and balances the factions).
Create small-sized maps (M).
I could provide a couple of maps (and you can choose from them), but what are the specific requirements? Are they purely for duels, or what? There are many options, which is why I'm asking... And the question of testers is still open...
