Why would it have been better off with a different name. I have many 4e D&D books, which in various ways contributed valuable content to my RPGing for several years. If the game had not been called D&D and published by WotC, it's very unlikely that most of those books would have been published. Which I think would not have made the game, or my play of it, better off.4e had some of these things, but as I've said before that game, which is quite well-designed in its own right, would have been better off with a name other than D&D.
