Online multi-player is difficult. You have to be able to keep the worlds in sync. In a first person shooter you can predict where players will move and then adjust when they are off a bit. With Kodu you can't do this kind of prediction because a single
keypress could create or destroy many characters. In order to work correctly all the character "brains" would have to be exactly in sync. We would basically need to do a complete rewrite to support this.
Another issue is how do we connect players with each other. Maybe here we could copy Minecraft and just allow local connections. It would definitely be easier to implement since we wouldn't need a server for hosting. Plus it would have the benefit of
keeping games local which is good for privacy and keeping unwanted players out.
As far as the "Kodu is slowly dying" comment, in June 2012, when the original post was written, we had ~18k new installations. This past June we saw ~76k new installations. These numbers come from our instrumentation reporting so do not count the people
who turn off instrumentation. Overall Kodu continues to grow steadily year over year.
