I second RC's objection to this rude and disheartening position. Further, my sympathy has already been taxed by Mike Mearls claiming all roads lead to Rome since before 4e even came out. I don't want go to Rome. Since I play Pathfinder and FC now, I'd say my road leads to Byzantium or something.
To me, that's the same as saying that where D&D is concerned, there is such a thing as "BadWrongFun."
I've played 'em all - OD&D, Basic, 1,2,3,4, Pathfinder, and likely some I've forgotten - and as long as the group of people I play with is a good group, I've gotten the same level of thrills, occasional corny jokes, exciting roleplay, and occasional thrill of a victory snagged from the jaws of defeat. (Well, maybe not with OD&D, I've only ever played it at one-shot con games.) I empathize with Mearls' sentiments exactly. To me, All roads not only Lead to Rome, they are paved with the same color of bricks!
Still doesn't mean I'm coming back to DDI, or using their Virtual tabletop - it means I understand Mearls, and what some people in the thread don't realize is that he agrees with him! He's gone on record, on ENWorld no less, as saying that every game company understands the big secret -- that we gamers don't really need them, ever since Gary and Dave let the genie out of the bottle some thirty - odd years ago.
However, every generation needs something different to attract new blood (my sentiments, not his), and that's what new editions are for. Stick to loyal rhetoric for any edition you want, the same rules aren't going to appeal to new generations over and over again as a general rule, and the majority of people playing the game's culture changes, so the game needs to change, too. But the goal of the gaming companies, and SHOULD BE OUR GOALS TOO, if we're interested in growing the hobby base, is to get the same outcome as every generation before -- players reliving moments from the table in conversation, plotting how they'll make their characters better for next game, talking about how they can't wait for the next session, and sharing it with the next person to come along.
