Again I think the vote will be determined by the nature of the audience of rampancy.net; with all the die-hard Bungiologists congregating here it's pretty much certain (IMO) that "Campaign Solo" is going to win out as folks grind through to get the story with a minimum of distraction.

I do see some advantages to co-op (more eyes means fewer cues missed) but some disadvantages (co-op's necessary chatter accidentally overrunning in-game dialog) too.

-- Steve'll run through solo the first time... but that's 'cause he hates screwing up so much in front of an audience.
