We certainly made a lot of mistakes on the MP front and have been working on fixing the problems,but you're right that we couldn't deliver it all fast enough. Our plans for lobbies for the non Steam versions depended on a piece of software that didn't materialize as fast as we thought it would and that is how we found ourselves doing things like the Global Chat and direct IP connection (which since the latest patch is a lot easier as it's linked directly to the user in the Global Chat).
There are people playing MP, but the most popular mode is the MP campaign and that's something that is typically played between friends because of the time you need to invest, so you won't see a lot lobbies that are open to all for that. Still, there's new content coming to DC which you'll get in upcoming updates and we are continuing to improve the gameplay.
