The game is FAR, FAR more "explosively popular" today than at any time before.What made D&D explosively popular was a combo of Basic and AD&D. Forget the clunky rules engine, It was the excitement, the danger (yes PCs died! often), the unknown, the interaction. Hasbro could mothball the I.P. but NOT the game. Gygax's 3rd edition of D&D, as he called it, would live on. Many other fine examples would too.
I get that some people prefer the old game more, but those people are a minority. I played it throughout the 80s and loved it. However today's game is much better. That is my opinion and it is also the opinion of most players.
