That is impressive. I host a fair amount at home but do rely on lots of cloud services too. My doorbell won’t ring on all my smart speakers if the internet is down!
I’ve been using Emby for a few years after Plex just became worse and worse, relying on cloud logins and being unreliable, pushing their own junk content above my library etc. Emby reminds me of what plex used to be, it’s amazing!
I use parsec to play retro games with my mates by streaming from my pc. Works really well!
