I've been playing with multiplayer games that run over SSH; right now I'm trying to push the framerate on the games as high as I can, which is what got me thinking about my networking stack.
I mostly use go these days for the backend for my multiplayer games, and in this case there's also some good tooling for terminal rendering and SSH stuff in go, so it's a nice choice.
(my games are often pretty weird, I understand that "high framerate multiplayer game over SSH" is a not a uhhh good idea, that's the point!)
