#Stellaris is on lowest price sale on Steam this w/end. v 2.0+ is well worth playing, despite neg review hysteria, but the full story DLC deal still comes out to over €55. Still, if you're able to commit the time, it's a galaxy of content.
I don't understand why the Paradox deal on GOG leaves out all their Grand Strategy blockbusters (CK2, Stellaris, HoI4, EU4). Lots of gamers would rather eschew Steam & support GOG these days.
