Ultimate Admiral Dreadnoughts and Sword of the Stars 2.
part of Sword of the stars 2 is even now it sometimes gets so laggy that you can’t finish a game. You just at some point declare that you’ve snowballed enough and can’t be beat anymore.
Hundreds of hours.
Ultimate Admiral Dreadnoughts is at least getting better now that the devs have abandoned it and modders are taking over.
I run both on my unraid NAS. I use plex for streaming to my phone over cell data. I use jellyfin for streaming to my laptops and TV.
Plex tends to break every once and a while though. Not often, but it happens enough that I’m replacing it with just having my music on a DAP that is synced with Syncthing.
I also use the comic viewer function of jellyfin.
