Thank you DeathByDenim!
This repository holds configuration and setup of diverse game-servers. It is written for Debian 11. There is a main setup file for installing necessary dependencies and adding a user "onfoss" to start all games. Game-setups are separated into directories!
Sadly not every game-server does allow for 100% automation!
