Sigil is No More

The 3d VTT made by Wizards is being shut down (in a year). This was massively expensive, but not as much as the "buying a studio thing" they stumbled into.

This is likely the death knell of this edition of the game. 2024 D&D was built for this, and even the new systems put into the game (bastions, removing RP abilities) were designed to support it. Now, we have an edition of the game that promotes abandoned features and a more VTT-focused experience that may play better on 3rd-party VTs but lacks interesting exploration and roleplay features that many want.

Past this, I don't see how they move forward without designing an entirely new edition of the game. This one supports dead digital features.
