Magic: The Gathering: 2 Open Source Clones Compared
Forge is an independent, actively developed rules engine (not tied to any single original release) that runs on Windows, Mac, Linux, and Android without needing original game assets; it supports online multiplayer, Java-based modding, and multiple single-player modes (Adventure, Quest) plus AI-opponent Sealed, Draft, Commander, and Cube play. Shandalar instead is built on the actual 1997 Magic: The Gathering: Shandalar game code, later extended with cards up through 2015; it's Windows-only and its development has halted, with only a single contributor.
