Lifthrasil: As far as I see it, this is the worst case of DRM yet. Even worse than Nex Machina, where some levels are locked behind a Galaxy requirement. Now, in Northgard, it's the entire solo mode.
Time4Tea: I'm not sure if it's quite up there with GWENT (being an online-only game with microtransactions, made by CDPR themselves), but yes, there is no question it is DRM by any definition.
So, hang on ... if the SP mode for Northgard
requires Galaxy, is there even an offline installer for it?
AFAIK, solo mode is not a synonym for single-player. There is also single-player campaign mode, which does not require galaxy.
I don't have the game, but I'm guessing solo mode is like skirmish mode in other games. Someone correct me if I'm wrong.
P.S. For now, I think we may still assume that this simply be a bug introduced in the last patch.
