OK, let's say, just hypothetically, that in a few years Wizards of the Coast decides that D&D, the tabletop roleplaying game, just isn't making money the way they want. Maybe it isn't even that--for whatever reason, Hasbro sends down the word that they're gonna just sit on the D&D IP--they'll license some video games, authorize some more really bad Forgotten Realms novels, but they won't be doing anything more on the pen n' paper RPG side of things for the forseeable future.
My question is, what do you think would happen to the current pool of D&D players? Would a large chunk stop gaming? Would they keep on, bereft of DDI, using their 4e books until WotC or whomever came along and revived things? Would there be an online "4e Simulacrum" movement? Would any return to earlier, OGL-derived games? What other gaming companies might see boosts if that were to occur?
I certainly don't wish or even suspect this will happen; I'm just interested in hearing how folks think such a momentous event for our hobby would unravel. If you're a dedicated 4e player, I'd also be interested in what you would do, if such an event occured--business as usual, or a sign for a big change?
