Fans of the old-school fighting game Heroes of Might and Magic will appreciate the new additions to the game. These improvements include a more accurate spell description and spell duration. The new version also supports hotseat multiplayer, although full online multiplayer support is still in the works. The game is currently at version 0.9.3, and the developers are taking donations via Patreon. Players can also support the project by contributing to their rewards.
The fheroes2 project is a free and open source reinterpretation of the classic HoMM2. The game was rewritten from scratch, and it is optimized for modern Macs. You will need to have the original HoMM2 files, but these can easily be downloaded digitally. The download link for the demo will give you a chance to try it out before making a final decision.
