On a side note: I tried to look around but couldn't find a straight answer - does disabling updates in Steam work for this game, or does the always-on force you to update to play?
Seems to be pot luck. I disabled updates for Deus Ex HR and it skipped all of them till I let it update. I disabled them in Borderlands 2 but it made no difference, every last update applied. There must be a reason, I just haven't found it yet.
