Introduction of Haven in the Stronghold vs. Dungeon tournaments.

Besides, within the modern template editor, you can create a template where both players start with a playable situation (for example, by creating a set of mandatory objects on the starting spawn points). Unfortunately, the template editor doesn't launch for me because my computer only runs in safe mode, so I can't create such a new template yet. It would be great if someone took on this task; it would be a new game mode, unlike anything else.

As far as I know, that template editor creates templates exclusively for the HotA version, where the Overlord expansion is already integrated. But here, we're discussing the Overlord expansion in SoD. It does have a template editor, but it's very limited, and you can create templates without it, but with the same limitations. Unfortunately, you can't do what you're talking about in SoD. There, the placement of objects is based on value. And for the same value, a lot of different objects can appear.

In general, anyone can create templates. There is plenty of information available for this.

M200 is an interesting format for some, but many don't like it because of the small number of zones, and you can't really explore much in the late game. And if you're unlucky with the layouts and heroes, it's extremely difficult to succeed. But there are interesting games sometimes, of course. I personally like this format, but for now, it's just like that. In general, tournaments are sometimes held in this format, so if you want, you can watch and participate.
