NASA is doing its own MMO. This must mean an opensource MMO engine either already exists or will soon exist. Its time for Roll your own MMO or ROMMO. A way for programmers with god-complexes to create their own worlds and impose their own rules on unsuspecting users who have been lured with friendly viral invitations. This will be much better than Facebook at wasting developers and users' time. On top of that each world creator will be able to design his or her own virtual currency, which will soon make everyone richer and richer, in a virtual sense.
