How to change the map size, starting year and company limit on your OpenTTD server

This article covers the world settings on your PlayNHost OpenTTD server and, importantly, when each one takes effect.

1. Understand which settings need a new map

• Map size and starting year shape the world when it is generated. An existing save keeps the size and history it was created with.
• Company limit, player limit, autosave interval, pause when empty and server visibility apply on the next restart, on any map.

2. Change the setting

1. Log in at https://panel.playnhost.com and open your OpenTTD server.
2. Go to the Startup page at /startup on your server.
3. Edit the value you want and save.
4. Stop the server, then Start it again.

3. Generating a fresh map at the new size

The server continues from the newest save it can find. To generate a new world at a new size:

1. Stop the server.
2. Download anything you want to keep from the save folder.
3. Delete the files in save and save/autosave.
4. Start the server. It reports no save found, generating a new world in the console.

4. Note on player and company limits

The player limit is set by your plan and cannot be raised beyond it. The company limit is yours to choose, up to OpenTTD's maximum of fifteen.
