After having checked out Plex, Jellyfin and Emby I’ve decided the latter was still my favorite. Jellyfin just isn’t there yet, lack of built in image-scrubbers, intro-outro-detection and quality clients just makes it inconvenient for me. Plex’s external authentication makes it a no go for me.
Emby is the only one that’s focused on what it tries to achieve and delivers. Also the support team is super helpful and pushes out fixes in a pretty good time. Not FOSS though
In a similar vein, though more about video-games themselves, I can also recommend Dungeon Hacks: How NetHack, Angband, and Other Rougelikes Changed the Course of Video Games by David L. Craddock. (For those who are interested in DungeonCrawlers and their origins)
