Internet spaces like this are going to be more refined and organized in the future, especially when the next generation of people grow older and take up the mantle of leadership, particularly within the academic sphere. Virtual worlds, and by that I mean MMOs in specific and everything techy in general will be cataloged, debated and critiqued, and most of all, kept for future generations to peruse at their leisure.
I'm not saying that every game made will be available for anyone to play, instead, I envision a time when certain games are given the "Classics" brand and resold to consumers at the 2100 version of Barnes and Nobles. There might very well be a Shakespeare of our generation lurking within a PC or console title, and a hundred or even a thousand years from now, college professors might be dissecting the narrative of World of Warcraft.
I imagine societies and organizations dedicated to the preservation of video games of all types, and a type of virtual tourism, where we can visit the Yosemites and Yellowstones of these worlds (Storm Peaks and Grizzly Hills), and my kids and their kids will marvel at 8 bit graphics and sidescrolling sprites. With the emergence of this digital holistic medium, there will be those guardians that will harbor the articles of the past for our progeny. They will be the ones sitting in the virtual trees saying, "I defend this code with my life," as the authorities rev up their computational chain saws.
