Wouldn't I have learned so many different approaches if I had provided a starting save?

There will always be several approaches, as well as different ways to complete the game, even with a starting save, but then all players are in EQUAL conditions, which allows comparing the results...
one will complete the game with 10 fairies, and another will need 20...
one will lose 2 troglodytes, and another will lose 10...
and what is there to learn?
all options can be calculated and understood, the interest lies in the competition...
would you be interested in running, say, 800m if all participants started not from the starting line, but from different points, but the finish line would be the same for everyone? as a result, someone would run 500m, and someone would run a kilometer...
the point of offline mode is to complete a given map faster, but at the same time, the starting save is set initially to ensure equal conditions for all players...
you can't compare apples and oranges...
and in principle, it's already clear which cities with which heroes are the fastest, all the theory has already been written and broken down, so all that remains is the most difficult part - practice...
therefore, it was necessary to: test the map - with which hero it will be faster to complete, then start the game with that city and hero with optimal object and guard generation...
and then upload the map and save for other players to complete as quickly as possible...
as a result, it turns out that it is incorrect to compare the results...
I played the map once and won't replay it, 34 is a very bad result, it was really possible to complete it 2-3 times faster, but I hate restarts and replaying uninteresting maps (some may think it's a silly excuse, but that's their business)...

therefore, it should not be surprising that there are no participants, saves, and everything else, most players are not interested in "how to cheat the AI on difficulty 200%", they need "something special", to create interest and challenge...

After completing Leonid1, I started thinking about other starting castles.

It is worth being more attentive and respectful to the players of this forum, especially to such ones....
Leonid1 is one of the few on this forum who calmly and adequately answers all questions and tries to explain things that don't even need to be explained.
and there is no reason to doubt the gaming experience and skill of Dirty and Leonid1, if you look at the forum, the results of online and offline games and tournaments, they are not in the last places there.

I am not interested in the results of the player Dirty.

And what is the point of posting the result if the organizer is not interested in the results of other players, especially more experienced ones?
