I want 2011's EPT too...but the first one was a result of decades of invention and creation. Will we even notice 2011's EPT, most people in the RPG hobby never noticed the 1975 EPT even when it was published by the biggest publisher in RPG-land, most have still never played it and most never will.
There were no boundaries recognized for the world of Tekumel when it was first invented and then hammered into a D&D-like game. Modern RPG campaigns have lot's of boundaries and boxes folks are going to shove a campaign or game into. We could lose sight of it because someone shoves it in the wrong box.
What good is 2011's EPT if most folks simply rip it apart for a few pieces to shove in their plain old games? Is 2011 EPT fated to evolve in 2017's Swords and Glory to be followed by 2027's totally-unpronounceable-esoteric RPG?
As for Blackmoor, almost every DM since has done Blackmoor (many may have done far better) but we didn't do it first. We weren't the spark of original genius. There will be no Blackmoor but there might indeed be a Caverns of Thracia.
EPT and Blackmoor were both inventions of men who had no experience with RPGs as most readers of this most certainly do. Each of us has likely has decades of experience and has read many hundreds times more about RPG then either innovator was exposed to when they got to work.
Who has the decades of non-RPG invention that will let them come up with the 2011 EPT? Are they going to let us know they did it?
