Heroes of Might and Magic III: Horn of the Abyss

Every game you own, in one library

Connect a store once and everything you own there appears — Steam, Xbox, Epic, GOG, itch.io and Amazon, installed or not. EA, Ubisoft, Battle.net and Riot games join the same list when the desktop app finds them installed on your PC. One library, deduplicated. Free, and it takes about a minute.
