## What it is
VCMI is an open-source, from-scratch reimplementation of the Heroes of Might and Magic III game engine, licensed under GPL-2.0. It uses the original game's data files and adds modern features such as high-resolution UI, extensive mod support, a launcher, multiplayer lobby, and cross-platform play.

## Use cases
- play Heroes of Might and Magic 3 on Linux, macOS, Android, or iOS
- run HoMM3 in high resolutions with modern UI improvements
- install and create mods that add towns, creatures, heroes, artifacts, and spells
- play Heroes 3 multiplayer via a global lobby or LAN
- generate random maps including modded objects
- replace the aging original HoMM3 engine with a modern, extensible one

## When to choose
- you own original Heroes III data files and want to play on a platform the original doesn't support
- you want deep, conflict-free modding of Heroes 3 gameplay
- you want HD-mod-like high-resolution and quality-of-life improvements

## When to avoid
- you don't own the original Heroes III: Shadow of Death or Complete data files
- you expect full compatibility with HotA or WoG mods
- you want a standalone game that works without original game assets
