Other than games, anyone have good examples of real time multi user apps?
Even with things like docs and sheets, though the capability is there, I find myself rarely editing in real time with others.

If you're collaborating with other folks on a project, it's beneficial to see updates in realtime to maintain that one source of truth. Otherwise your work and theirs might overlap and someone will need to resolve merge conflicts. That, or you go the locking route, which comes with its own set of hassles.

My SaaS day-job is a real-time multi-user checklist web-app - built using SignalR.
We're able to fit tens of thousands of concurrent users on a single Azure AppService instance - and we're self-hosted so we don't have IaaS-rug-pulling-anxiety - PartyKit looks cool, but I take a long-term view (5+ years) before adopting a technology, and PartyKit's brochure website is lacking information in that area...
SignalR's two main selling-points back-in-the-day (2014-ish) was its solid cross-browser support and how it abstracted over WebSockets, Comet, SSE, long-polling, et al - but it's 2024 now and everyone's on Chromium or WebKit, so cross-browser support is moot, and and WebSockets+SSE now covers all use-cases; so there's less going-for SignalR thesedays, and since the ASP.NET Core rewrite of SignalR it just doesn't scale as well on the client-side (as it no-longer multiplexes multiple Hub requests over a single connection, which is crazy... and HTTP/2+QUIC+3 doesn't really help, I find).
