It's turn-based tactical strategy rpg. You have a castle that you develop each turn where you produce units for army. You have heroes that lead these armies and move around the map getting into fights, they level up which makes units under their command better. It's extremely addicting.

Yes but it's much better to install HoMM3 HD+ overhaul from
https://sites.google.com/site/heroes3hd which gives you modern resolutions and mod support. Also if you want to play multiplayer everybody also uses it to do so.
