That is not progress, IMO.
I must agree with you. I am quite sure there will be tons of new mmorpg's that are basicaly quite the same over 10 years for instance. Not only due to tools like RealmCrafter. There will be just so many that you must come up with very new origional features to become popular as there will be tons of mmorpg's. Sure, RealmCrafter is a good tool, but it does make it harder for everyone to lead a succesfull mmorpg as there will be tons of nearly the same. Even if they won't be the same, there will still be tons. I seriously doubt Solstar Games cares about this fact so yeah i agree with you.
