I agree, that is my one concern here. Being technical the patents are exactly how all multi-player online games are implemented. But there are not really many other ways to implement a multi-player online game though. So my concern is that WDDD just wrote down the instructions on how to build a multi-player online game and then sent those instructions to the patent office. They didn't build their own game though and this is borderline how a patent troll works if I'm not mistaken.
