Tried to look around, but couldn't find a conclusive answer:
Does it have DRM? Or could the player entirely on his own, including his own multiplayer server instance?

Thanks in advance!

You have to log into your account to play.

I see. That's sad. But thanks.

Depends on what you mean by DRM. By default, you need to log into the launcher at least once to verify your account, and servers need to be verified at least once too.

That said... The community found out that Hytale uses a system very similar to Minecraft, where it's easy to bypass and you can just set your server to not check the validity of licenses (allowing pirated copies to connect).

I see. That I'd call DRM already, and wish there was an official DRM free release. Thanks to you too.
