I’m keeping an eye on gamevault as well, but wanted to include to Retro gaming. I also like a web interface which gamevault is not currently planning on having. Right now I am experimenting with Romm. I can create a category for gog games and download each game as a zip archive. Not fully what I want but it works. I love that for a lot of emulators you can play roms directly in the browser.

I also saw mention of gaseous games and Gameyfin but haven’t looked at them to closely yet.

The major problem—one of the major problems, for there are several—one of the many major problems with governing people is that of whom you get to do it; or rather of who manages to get people to let them do it to them. To summarize: it is a well-known fact that those people who must want to rule people are, ipso facto, those least suited to do it. To summarize the summary: anyone who is capable of getting themselves made President should on no account be allowed to do the job.

I use organizr and haven’t felt the need to try anything else. It can host other sites in an iframe which really gives all the disparate apps a unified feel. Some sites can be a bit difficult to set up, but once you do it works great.
