Holy moley, man -- you don't quit, do you?"The game remains the same" was not in reference to board games. It was a selling point of 4E camparing it to earlier editions. My point was that either that is a crock of crap (in which case D&D does not play like a boardgame) or the current D&D game does indeed play like a board game,in which case "the game remains the same" was untrue.
D&D is *similar* to a board game in many ways. It is also *different* from a prototypical boardgame in many ways. Moreover, D&D isn't now meaningfully more or less like a boardgame than it has always been (despite the protestations of some edition warriors).
The boardgame comparison is for the benefit of people unfamiliar with tabletop RPGs. For those of us familiar with tabletop RPGs, including everyone here, we can (more accurately) admit that the differences between D&D and boardgames outweigh the similarities.
D&D has remained the same -- it is not a boardgame. However, saying that it's like a boardgame isn't "a crock", because that's also true. "Boardgame" is a fairly arbitrary category, and D&D definitely falls along its fuzzy, grey border.
