I'm personally making adventures. Mostly little 40-page books that allow a group to play to a story. These are OGL-licensed so I can re-print existing SRD monster stat blocks with the adventure for ease of use, but don't really contain anything that could reasonably be called WotC's IP beyond that.
Material for game campaigns; including new settings, monsters, character subclasses, extended rules etc.
Additionally also files for printing 3d minis and VTTs such as foundry, which doesn't come with d&d rulesets out of the box, but relies on community content to support it
VTT = virtual table top
To add another entry, D&D skits are very common on TikTok. Dead Gentleman Productions has made at least 3 D&D inspired (and using) movies, including:
- Gamers
- Gamers: Dorkness Rising
- Gamers: Hand of Fate(??? I didn't see this one, I think that's the title?)
And AD&D was used as a major story tenant of Stranger Things.
