Looking over the code it does not appear to actually do anything.

If you want something like this check out https://pterodactyl.io/

It has pre-built support for like 100 games: https://github.com/pterodactyl/game-eggs

Or: https://linuxgsm.com/ - 130+ game servers.

CLI only though, but really nice.

I wouldn't limit yourself to describing it as a game server daemon. It's effectively a IAAS / PAAS platform if you switch to a plugin model for those games. Well done.

Can you add a License to the repo please?

Be warned, no license listed.

Created 3 weeks ago. 27 commits, half of which seem to be version bumps.

Why should anyone want to use this, OP?

Strong suggestion, do not give advice without explaining any reasons or context

But why not tho?

It’s unclear if this comment missed the fact that the previous user was using mimicry as a rhetorical device to critique the original poster, or if it was an attempt at 'yes and'-ing by doubling down on the brevity. In either case, the question would have been more effective if directed at the grandparent comment, since that is the actual source of the unsupported assertion.

itzg's docker image for Minecraft makes life quite a bit easier - switching mod loader, versions etc. with environment variables is simpler than continuously downloading versions and juggling directories.

Why not? Docker is effectively free on Linux. You only get the performance hit on macOS and Windows (since it runs the containers in a hidden Linux VM).

IndifferentBroccoli do fine with thousands?
