I think perhaps I'm recalling impressions from news and info leading up to the kickstarter where I'm certain there was emphasis on 'single-player' specifically.
I can't remember how well I paid attention to the kickstarter info when it launched. With the impressions I had at that point, accurate or not, I jumped into the pool so to speak.
But lesson learned… forget whatever you think you read and hear about prior to a kickstarter but DO actually pay attention to what you read and hear about from the official kickstarter.
That is why I went back and looked to the kick starter page. I was like you or maybe I just wanted to believe it was going to be like the old days single player game.
