Just to let you know about this project (not mine), in case anyone is interested:
https://ihhub.github.io/fheroes2/

"Free Heroes of Might and Magic II (fheroes2) is a recreation of HoMM2 game engine.

This open source multiplatform project, written from scratch, is designed to reproduce the original game with significant improvements in the gameplay, graphics and logic (including support for high-resolution graphics, improved AI, numerous fixes and UI improvements), breathing new life into one of the most addictive turn-based strategies."

Very good. I'm happy that finally this game gets some love.

Never heard of it before, but after trying it out it looks to be expertly done so far. Love all the neat helpful details and QoL improvements.
Hopefully recreated single player campaign is as close to original experience as possible.
Anyway this project deserves more attention.

P.S. Just a note: if you want it to have cutscenes from original then you have to install HoMM2 Windows version (provided as a bonus download by GOG) which has a folder named 'ANIM', copy it to your FHeroes2 folder and it will work like a charm.
