An interesting tidbit might be that ED actually started out with a multiplayer - we actualy have a video of it which was prepared for a milestone. I'll see if I can find it and put it online so you can see from where we come. We dropped it because it indeed caused massive problems with the story, but that doesn't mean we haven't stopped thinking about it, and I think we've come to some new insights (which tbh I hope nobody else has had yet

)
When it comes to online play for RPGs I have come to realize there are competing aspects I enjoy, teaming, social, and story. A game world like divinity might be a huge success as an online world but only if you could find a way to make more of what is happening in the game the player characters story. On top of this I would really enjoy it if a lot of the 'story mode' of the gameplay was instanced so that puerile playstyles wouldn't disrupt what would have otherwise been a potentially inspiring or great moment of story telling.
For a lot of people the actual game of the MMo really begins at level cap. They laugh at and/or bulldoze through content as fast as they possibly can in order to get to that content milestone. Great for them as long as the game doesnt make the mistake of throwing only simple content at the player in order to support that particular playstyle only.
