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

That's funny :)

[/U]With these trends, soon, besides castles and templates, we will only be creating mods.

And what, it's an interesting idea. Is it bad if there's a choice?
No one is going to force anyone.

And what is Hota 1.3? Is it focused on game balance?

Hota is a separate, independent mod with its own features, changes, and balance, new cities, units, etc.

Hota and HD are different things.
The HD mod provides the technical part for more convenient modding, fixes bugs in the original game, adds conveniences in the form of additional buttons, but nothing more.

What I wanted to say is that whether it's additional content or a change to the rules of the game itself, it's, in my opinion, a function of mods.

The question was about a possible alternative to the true Soda-style gameplay in the form of removing unused objects/art, etc., and everyone will be aware of the changes if they are made. As an example, a mod for the M200 tournament.
