A world that stays on
With a dedicated server the world is still there even when you are not connected, and your friends join whenever they want. Nobody has to leave their computer on or open the game to act as host.
How many players
Pick the slots for your group and think about the hour when most people overlap. The game itself warns that with more than about 32 players the map can have sync problems, so for large groups it is better to start smaller.
Workshop mods
Steam Workshop mods are added from the panel and the server downloads them for you. Players also need the same mods to join, so share the list beforehand.
Memory and disk
Mods and the growth of the world use resources. Check how much RAM and SSD each server includes and that they leave room to add mods.
Included in every Project Zomboid server on LIZARION, whatever number of slots you pick.
Backups
Before adding or removing mods, or changing important settings, take a backup of the world. That way you can roll back if something breaks.
