Ideas and suggestions.

Well, even without Overlord Hero, green will move before blue and brown computer players. For the game itself, the blue player will move second, but with a green flag; even on the template map, it will be in the blue zone. Therefore, there shouldn't be any temporal paradoxes... Although, maybe I didn't understand the point of your post...

That's right. I didn't know that humans move before computers, even in normal mode, regardless of the colors they play.

In the fifth game, there are no rollbacks: the game calculates the shortest distance between opponents (that can be traversed) and includes alternating turns when they are "too close." As a result, collisions are impossible. Is it impossible to do that here?

It's possible. And it was initially planned. But it's not easy.
I don't know exactly how it works in the fifth game. But how do you think we should determine whether the distance is traversable?

Here, you need to take into account a lot of things. - the possibility of being destroyed and resurrected, control, the possibility of gaining control in that distant utopia, and whether the player will take that utopia; how to calculate whether the player will break through the block or not? After all, there are quite a few maps and templates where the opponent is within reach from day one, but the Overlord Hero doesn't allow them to meet for a relatively long time. If you don't take something into account, collisions cannot be avoided. If you make such an intelligent interruption too rigid, the Overlord Hero will end without really starting.

The only thing I understood from what you wrote is that you didn't understand what I wrote.

For convenience and to save time, before an intelligent interruption is made, the only thing that can be done is a manual interruption and resumption of the Overlord Hero. The nuances of scouting are not minor. These nuances can change the course of the game. By the way, with a hint, I came up with a situation where you can significantly sabotage the blue player's replay: when replaying, the blue player will not go to that distant utopia to lose half of his army for the sake of boots of resistance.
