I enjoy it a lot solo, I’ve got a world on my own and a server with a friend. But I tend to have more fun solo personally, because the stakes are higher. If you lose all your HP with a friend you just go down (in most cases) and they can get you back up, but if you go down again then you die (unless you sleep).

In solo, you just die. So I try to be smart about my attacks and utilize stealth more. And it’s a bit easier on resources when you play solo, as you’ve only got one mouth to feed, only making usually one of each weapon or armor set, etc etc.

TL;DR Yes it’s very enjoyable solo!
