Ballpark Estimates

These are approximate figures based on testing. Actual requirements vary depending on player count, mods, and farm complexity. Monitor resource usage and adjust as needed.

The server runs continuously (24/7) and uses resources even when no players are connected. For cloud hosting, factor in always-on costs.
