I've said about a thousand times, and will probably say about a thousand more, that D&D desperately needs a "casual edition" that comes in a single box including everything needed to play (1 or 2 rulebooks, sample intro adventure, dice, perhaps character sheet blanks), is streamlined and simplified enough that a player can start playing in 5 minutes and a DM can start running in a day or two, is open-ended enough that someone who wants to keep playing this version indefinitely can do so, but is also roughly compatible enough with the full/hobbyist version of the game that someone who wants more detail and options can switch over without having to completely relearn the game from scratch (or, with a little bit of effort, can mix and match elements between the two). Yes, I'm thinking of the early 80s split between Basic/Expert D&D and 1E AD&D (not the late 80s/90s split when the two lines became essentially redundant to each other, but specifically the 1981-83 "Moldvay" era where on the one hand you had D&D that was a simple-but-complete game for newbies and casual players, and on the other you had AD&D which was a more complicated cousin-game for more experienced and/or dedicated players, and while the two lines weren't totally compatible they were generally similar enough that if you "got" one you would probably get the other, and many people freely mixed and matched elements of both (consciously or otherwise)).
And yes, one of the reasons I'm saying this (besides the fact that I think it would make good business-sense) is self-serving -- even though I'm an "experienced and/or dedicated" gamer, I've decided that I don't want the full/complicated ruleset with all its options and detail and would be perfectly satisfied by (and in fact prefer) the casual/newbie version (assuming that, like B/X D&D, it would be open-ended and fully playable, not like the recent Basic Sets where you can play for about 2 sessions and then have to upgrade to the full version).
