Unless you need Fantasy Grounds Classic (FGC) to connect with an existing group of Fantasy Grounds Classic users, we highly recommend that all customers purchase Fantasy Grounds Unity (FGU). FGU provides the same level of features of FGC, along with numerous enhancements for images, map making, easier game hosting, better operating support for 64-bit systems, and numerous other updates (see topic below).

Only FGU will be receiving new engine updates at this time. FGC will be placed in maintenance support mode only.

If we add new functionality, fixes, or features to any rulesets you use beyond June 24, 2021, then you will not receive those updates in FGC. Your update button simply won't light up anymore.
