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

and there was something else I wanted to say: in HD, I won't be creating a new version for every minor change or option, as some would like. Firstly, it's technically more complex, more time-consuming, and requires more effort. Secondly, I don't see the point in having a choice: playing Shades of Darkness with X or Y percent of fixes. If it's going to be bug-free, then it should be completely bug-free; otherwise, it should be played with the original bugs. And I don't understand the complaints about having to coordinate with opponents to play with certain features. No one is surprised that to play with Conflux, collections, and other additions and fixes, you need to convince your opponent to play SoD instead of RoE. Or, if you want to play with features from Warlords, you need to convince them to play Warlords instead of SoD. However, SoD cannot play with RoE using RoE's rules, and Warlords cannot play with SoD using SoD's rules. But HD+ can play with SoD using SoD's rules – and that, in my opinion, is a significant convenience.
