Here is a guide on how to fix no/few servers showing up in Get Stuffed!.
How to Fix Empty Server List Issue
This is a steam problem and hopefully it’s fixed soon!
First: Open up steam and go to the top left of steam and go to settings.
Second: Go to downloads.
Third: Change your download region to a US based region.
Forth: Restart steam when it asks you to.
And that is it, now simply start the game and you should see a lot more servers.
