Oh it's okay, it's a single-player game, it's not that you need any server capacity for that. Other than download servers but it's Steam's problem, not publisher's.
...right?

But there's optional Cross-Platform save sync (independent of the steam one) and multiplayer.
Anyway, as a person who bounced off of the previous entries of this genre I'm really enjoying this one, and I'm very happy for the success the studio is having - they deserve it!
They had Twitch integration since the beginning and judging by some accounts they weren't prepared for how much that would be in demand on full release. Each user can see streamer's full inventory and journal, vote on dialogue options when asked, etc. Surely Steam isn't handling that.
