Aye, there's the tricky part. A much broader thread would be, "What is it that makes D&D the game it is?" You have the six abilities, the classic core races, the classes & levels, particular class features, the slot- and recipe-based magic system, the specific corpus of spells, and the combat and skill systems—which have changed from edition to edition, but there's a recognizable thread nonetheless. Of all of those, I think you could drop the races and the classes and still have something very recognizable as D&D, particularly if you keep the special abilities generally the same—it's just that they aren't siloed arbitrarily, but by prereq chains at most. Prereq chains, though, are halfway to classes already, which is why I suspect there's little incentive for a freeform system for D&D, even if D&Ds class-based system makes many possible concepts difficult or unviable.Hm. The idea is interesting, but I have no idea how you'd do it and still claim to have D&D when you got done with it.
But the NERO larp managed a hybrid class/point-buy system, barring some complaints about rogues being overpowered. Of course, their corpus of spells and special abilities and such is vastly different from D&D, even if the character classes are the archetypal fighter, rogue, arcane (celestial) caster, and divine (earth) caster. Not that I expect to see many people here who know much about NERO.
