Heroes of Might and Magic III
Heroes of Might and Magic III is still the easiest old strategy game to recommend: easy to learn, endlessly replayable, and still supported by major community projects.
Best place to start is the GOG Complete edition, then add the mod path that fits you best.
Mods
Community picks
HD Mod
Resolution support, cleaner interface scaling, and the best quality-of-life starting point.
Horn of the Abyss
The biggest expansion-style community mod, with new content that still feels close to classic Heroes III.
VCMI
Open-source engine route for broader modding support, portability, and long-term community experiments.
ERA 3
A Wake of Gods and scripting-heavy platform for players who want bigger overhauls, mod stacking, and deeper experimental content.
Legacy of the Silence
A huge ERA-based expansion with many extra towns, 8th-level creatures, new artifacts, and a much more chaotic high-content sandbox feel.
