I have to admit that the state of the dialogues in c-op is worrying. The co-op gameplay has been a key concept from the start, and even way back at the first videos there was some co-op play shown. There was co-op play shown off many times in the pre-alpha kickstarter videos months ago.
And yet, after all this time, there are still obvious issues like it being impossible to follow a conversation your partner is having with an NPC, and the second player having no context for the dead-guy book conversation, they just get dumped into a dual-dialogue? These are pretty big issues for co-op play, and no one's thought of those at this stage?
