I remember that back in the day, there was a practice where a pair would generate a mirror map and send it to a neutral observer to check with cheats whether it was generated correctly. I myself acted as this observer a couple of times.
And after the check, they would proceed.
Why not? The War of the Titans community has always been characterized by maximum flexibility in finding solutions to problems.
(Of course, there's a desire to have a mirror map in the template pool – the best of the existing ones).
What's so outstanding about the h3dm1 template? Is it just that it's the very first of the mirror templates? In my opinion, the gameplay on it is usually drawn out. There are more interesting mirror maps – h8mm6, for example. Especially if you play with a map preview to check for bugs.
I haven't seen a diamond mirror map, but it should be better too; I wanted to create one for War of the Titans back in the day.
I'm not even talking about hexagonmirror or seafarers.
Although, if you create a map similar to h3dm1 for a medium size, it should be more dynamic.
The structure of a mirror map template can be anything, and it would be strange to assume that the first step in this direction was the most successful. Although the template is not bad, of course.
