I mean the fact you include GURPS (and frankly lets be generous and say RPGs) as part of that legacy speaks to it transcending mechanics and really being about goals.
I agree completely. And agreeing to terms here is critical.
I've been in multiple "is 4E D&D?" debates, and consistently I find that it is a stupid question.
If GURPS *IS* D&D to you, then you SHOULD be generous and, at least, include all fairly standard fantasy RPGs. And that is a good place to have that a solid conversation. But in that place the question "is 4E D&D?" is stupid because the definition of D&D is so wildly open that of course it is and saying so doesn't offer any useful information.
Or, you could be in the D&D is THAC0 camp. And that is a great place to have a solid conversation. But in that place the question "is 4E D&D?" is stupid because the definition of D&D is so clear that 4E obviously is not.
In the end, if your definition of "D&D" includes both 2E and 4E, then it is impossible to not reasonable include a range of other games that just don't happen to have the brand name. If your definition of "D&D" excludes all versions without the brand, then it must exclude some with the brand. The remaining option is that your definition of "D&D" is irrational and inconsistent and that is not a good place to have a conversation.
In case I spoke poorly, none of those "you"s above are anything but generic.
Part II
Success is very simple, I think, if you pick a certain context and define success by their accepted parameters. I don't know if I believe in any sort of 'universal' success.
I get the feeling you're looking at success from a marketing and profit growth standpoint as it pertains to a singular brand, D&D, in your example. In that instance, you got me. I have no idea. That, as everyone loves to point out, requires sales figures. We all have our hunches and that's honestly fine. All I can say to that is I enjoy the game, others enjoy the game, I know of new players who have become gamers through my edition of choice, I'm excited for the future of my edition, I'm actively working on contributing to it, and all of those to me are successes. I imagine the OSR crowd feels the same with their edition, and PF with theirs, and GURPs and SW and Savage Worlds theirs.
I would like to close out by saying I honestly do enjoy our disagreements hehe.
I think the changes made to the brand were designed NOT in an altruistic effort to increase the fun of a select group of people on the assumption that those lost would just find something else. I think the changes to the brand were designed to increase the fan base.
I think they failed.
I don't need sales figure for that to be a reasonable conclusion.
I'm not claiming that they lost X%. I don't know. And, really, I'm a huge fan of the DDI model and wouldn't be surprised if their "SALES" are doing quite nicely because of that improvement alone.
But I don't own any Hasbro stock and I don't have any reason to care on that front.
As a fan of the hobby I am interested in how the flagship brand is doing.
And, just personally, I looked at the plan as they described it in the roll out and saw what, to me, were obvious flaws from the beginning. So, certainly, there is a childish "I told you so" pleasure in saying "I told you so".
But I 100% agree that as long as everyone is playing what they want and having a good time then THAT is what is important.
If I wanted to argue about important stuff, I would not be here. I would be over on a political site somewhere. I can get into some great political debates. But I REALLY care about that and it stops being fun in a hurry.
RPGs just happen to be my hobby, so I care enough that I'm interested and paying attention and can become invested in a debate. But, at the same time, I don't care so much that I feel at all emotionally invested in the topic. So I can argue, and it stays fun.
