I also made pretty heavy use of plugins to manage PCs, NPCs, encounters, items (!!), custom tables, maps, and setting details in a single campaign. Led to a lot of bug reports for the D&D-specific plugins, but Dataview worked like a charm.

Having a more Obsidian-native interface for managing all of that is. Like other commenters, would definitely watch a video of you sharing your Obsidian "build" for that use-case.
