VCMI is an acronym of the Quenya phrase "Vinyar Callor Meletyo ar Ingoleo", meaning "New Heroes of Might and Magic".

I wish it worked with HotA but it is nice to play natively; though even run through emulators HIII is fast enough.

There is a partial HotA port: https://github.com/vcmi-mods/horn-of-the-abyss (available in the launcher to install)
