All things considered, I'd rather have the Steam version if only for the ease of Steam, but for you luddites, find some filler and get your disc copies.
Sorry about the ending on Nov 5th thing, I only c/ped what Steam themselves said.
Original Steam deal post follows
A good deal it would seem for this RPG.
EDIT: Mini review after spending 8+ hours straight playing it:
TOTALLY WORTH IT.
Also, this game is like Dark Messiah in that it got a lot of bad rap for bugs I just don't see in my playing. I've seen one buggy interaction, one crash (Likely my anti-virus's fault), and one map-stuck glitch. That's pretty much it.
