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

Well, if you can't live without plugins, then don't update HD. What's the problem?

I'm sorry, but this update makes me think that the Heroes team is afraid that someone will steal their thunder.

Good lord, let them.

Removing plugins is a major blow to the entire community.

I don't think so. There are more people who just want to play the game than those who need a complex editor. However, if you are still interested in future versions of Heroes and HD, then once again, write down what specifically you are missing.
