Posts from HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Obelisks are just experience and skeletons. And simply interesting blocks. I don't believe in any mythical value; the difference in respawn points based on the content can be so huge that obelisks are insignificant compared to that.
Water artifacts are also a plus; they reduce the imbalance of Utopias, when one player gets 2 and another gets 5. Besides, Utopias are often taken for money, not for artifacts, and they always give money for them.
I don't quite understand why you want to change SOD when there's VT for SOD, where all this stuff like 3 stacks, 2 levels, the absence of obelisks and cartographers, etc., is implemented. Play it and enjoy.

The fact that water artifacts reduce the imbalance of utopias is news to me.

play the regular templates with patch m200, you won't get such luck

We play a game on 3.45. When joining the game, this message pops up:

About two weeks ago we played and everything was fine.

Correct. Only it's been removed from the rules. And there's value, but no use. An inconsistency.

Maybe it's worth implementing a tournament patch that incorporates all the HeroesWorld rules? (for example, it would be physically impossible to upgrade fairies or have more than 2DD, etc.) how technically feasible is this?

HD+ is created not only for HeroesWorld, many people play this version and therefore removing from the game what is not allowed on one resource but is allowed on another is, in my opinion, incorrect. Connecting a module like m200 is the most normal option. IMHO

So, with water artifacts, one gets a Water Bottle and КЗ, and the other gets a Captain's Hat and Boots of Levitation. Interesting, if these artifacts weren't present, how could one imagine the imbalance?

The entire post is epic nonsense.

Instead of obelisks, gold and 1-2 level creature dwellings are generated, guarded by, yes yes, experience and skeletons. "Interesting blocks" - of what? The fact that water artifacts reduce the imbalance of Dragon Utopias is completely News.

One has 4 Dragon Utopias in a 3-player game, the other has 2. Isn't that imbalanced? Besides, I personally find Dragon Utopias annoying in random templates, where on the same Jebus Cross several alliances of angels gather. Dragon Utopia already gives a large sum of gold, which fully justifies taking it. Artifacts are just a nice bonus. And you want this bonus to be mandatory. Shame on you!

Well, first you should think with your head, if you have something to think with, maybe then this news will reach you, and you won't first write nonsense and then try to argue.

Well, that means the opponent either doesn't have HD+ or updated their version.

One has 4 Dragon Utopia in the treasure zone, the other has 2. Isn't that unbalanced? Besides, I personally find Dragon Utopia annoying in Wastelands, where on the same Jebus Cross several alliances of angels gather. Dragon Utopia already gives a large sum of money, which fully justifies taking it. Artifacts are just a nice bonus. And you want this bonus to be mandatory. Shame on you!

It's amusing to see players of the HD mod (formerly SOD) still complaining about the direction of some changes, for example, in VT. You haven't played the original SOD for a long time – the map generation has changed, the objects have changed (Naga Bank), not to mention the transfer of troops. Let's just calm down about this (or admit to ourselves that it's time to move on from building second-tier structures, having three stacks, and removing water artifacts).

In my opinion, since you've already reached the point of making changes that directly affect the game's mechanics, it would be better to do it more officially and ask players what they would like to see. You can't just introduce things like nagabanks and obelisks in regular updates. Ideally, in my opinion, this should be done in a separate patch, like M200 - (like regular_HW, as Leader wrote). There shouldn't be any problems with using it (some people are worried for no reason), but if you add everything to the main version, then you definitely won't be able to avoid problems.

Don't confuse things. HD only provides minor bug fixes and interface improvements, while BT implies a completely different game dynamic, primarily the absence of morale and global skills, the addition of 3 stacks and 2 levels, secondly, experience potions, etc. The ban on water artifacts, gold instead of scrolls, etc., are all minor things that SOD players could easily accept without any problems, but many will never be able to accept the absence of morale (in BT, this is a sacred canon, however regrettable).
