I don't think Hasbro/WOTC entirely cares if you think it's D&D or not. Clearly the hobby has been suffering as of late. The question truly is, can we get new people coming into the hobby who think this is D&D? Or.. are we going to lose the war to the electronic media?
Because gaming on the whole is going up. But non-electronic gaming is going DOWN.
As for me, it's D&D, because the controlling company says it is. Is it an optimal fantasy roleplay? Who knows. Everyone's got different opinions on that one. By and large, though, we'd all better hope it's successful. Because if it's not, and if Wizards goes under, we have some pretty significant problems on our hands.
My FLGS now is being kept alive not by RPGs, but by Games Workshop. If RPGs stop doing well, if this game fails, he's just going to dump RPGs entirely and go to board games, comic books, and minis.
And he's on an "industry" bb and, from what he's told me, he's not the only one about to do this.
