PvE pretty much is the game. PvP is in there but it is a tucked away feature that you probably won't see a lot of use from as all players have it deactivated by default. And due to the way the game is structured you will probably not spend a lot of time playing in the company of total strangers.

But all around the difficulty is quite low unless you go to a biome before you are meant to, in which case you may just get one-shotted. But fortunately most enemies are pretty bad at navigating the procedurally generated terrain and you will probably be cheesing a lot of enemies almost on accident.

The pace is really slow though, especially if you are playing alone. You will spend a lot of time facing tasks that don't pose a challenge but nonetheless require a big investment in time to actually do. Survival games in a nutshell.

Making a little house for yourself doesn't take much time though and it's nice to see it grow as you get better with the building mechanics. It just needs some more parts.
