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

Here, someone already pointed out that the patch is geared towards the majority, and it just so happens that in the third game, it is exclusively a Multiplayer experience.

Basically, what I've been saying: the community is divided based on preferences. If you play Jebus, go to Hota; if you play Singleplayer (where 95% of all maps are), go to SoD.

I think you have a somewhat unrealistic view of the Heroes community. Let's look at the Russian-speaking audience of Hota, for example. The Hota group on VK has over 23,000 members: https://vk.com/h3hota. The online lobby has slightly fewer than 15,200 players who have played at least one game (see the rating window). The audience there is divided into Russian-speaking, English-speaking, and Polish players, and there are at least as many Polish players as Russian players. That is, there are no more than 8,000 Russian players. And this number includes those who played once and quit, those who play against the AI in pairs, etc. There are only a few hundred serious players, like in this community. That is, the number of Singleplayer players clearly exceeds even the number of the most novice Multiplayer players (15,000 : 8,000). Obviously, Singleplayer players are the majority among the Hota audience. Plugins are practically not widespread among the Russian-speaking audience of Hota. They are discussed on some obscure forums (I'm not counting the English-speaking HC here; among Russian forums, I only know handbookhmm, and I stumbled upon it by chance). In the Hota VK group, plugins are not discussed, as far as I can see; no one has even expressed an opinion about disabling them (in the HD group, there is 1 question, in the df2 group, there is 1 question, here there is 1 question). And in general, the question "How to Download?" is quite common, let alone plugins. In my opinion, at most a few dozen people (or even fewer) use plugins. This is a negligible part of the Singleplayer audience of Hota, so disabling plugins doesn't change anything for most Singleplayer players of Hota. As for the English-speaking audience, plugins are more common there (HC). But the reaction to the update clearly does not correspond to the hypothesis that the update ruined the game for many thousands of Singleplayer players. Obviously, this update changes a lot for you personally. Perhaps it also changes something for a few dozen other people. But the words that there can no longer be a Singleplayer experience in Hota after this are ridiculous.

By analyzing the changelog of Hota, you can see that 75-85% of the changes relate to Multiplayer. If you remove all the tournament threads on this site, there will be a couple of hundred with infernal questions in the spirit of "wHeRe To dOwNlOaD hErOeS3".

Most of the items in the changelog are relevant to both Singleplayer and Multiplayer. Of course, there are things that are done specifically for Singleplayer and purely for Multiplayer, but the latter clearly do not make up the core of the content. If your numbers refer specifically to new features that are not relevant to Singleplayer, then they are quite dubious. As for this forum, it is simply a forum for Multiplayer players (and quite advanced ones). Singleplayer players hang out on other forums and on VK. They used to be here too, but most of them have moved to platforms that are more convenient for them.
