I think 4e was a great game, and its "failure" (ie that it is no longer being published) is obviously due to the "intransigence" of a segment of the playerbase (ie they didn't buy it).
You seem quite intransigent about this viewpoint, pemerton, which implies that the reason people didn't buy into 4E was out of intransigence, which implies wilfullness, rather than the possibility that they simply didn't jive with the rather specific and historically-divergent approach to D&D that 4E offered.
With regards to 4E, I've seen three general camps:
Camp One loved it and thought it was the creme-de-la-creme of D&D, or at least the best thing so far.
Camp Two hated it and thought it was an affront to "Real D&D."
Camp Three was somewhere between ambivalent and liking it, enjoying it as an interesting variation of D&D but also feeling that it lacked something that other editions had.
Presumably you are in Camp One, and I am in Camp Three. Your view seems based upon the idea that only Camps One and Two exist, when in truth I think that Camp Two was simply a vocal minority and that most non-Camp Oneists actually liked the game or, at worst, were ambivalent. The simple fact of the matter is that a lot of Camp Three folks played 4E for a year or three but lost interest and moved on to something else. For whatever reason 4E didn't seem to capture this large segment of the community--which may even be a majority--like previous editions did.
So my question is, can you see reasons for 4E's publishing demise that wasn't simply the ire of Camp Two and the supposed intransigence of Camp Three? Or do you think that Camp Three's lack of adoration is also due to intransigence?
EDIT: I think Camp Two was rather large in the first year, but that many moved on to Pathfinder or retro games and didn't look back. So I do think that there is intransigence there, but that Camp Three folks (such as myself) actually played 4E for several years but tired of it. I'm asking you why you think that might be other than intransigence, because playing for two or three years implies that there wasn't intransigence. Not-adopting implies intransigence.
(Now I'm tired of using the word intransigence, which I've used more in this post than in my previous four decades of existence)
Firstly, I am upfront that this is my experience and that the experience of other people may vary.
Secondly, I think it fair to distinguish here between the conversations of char-op types (or any other small subset of the larger community which develop their own jargon not actually found in the game) and your more regular gamer.
But here is my take, and its just my opinion on the matter from an outsider's perspective (outsider to 4e)....
4e lent itself to a more mechanically oriented talk than other editions of Dungeons and Dragons. Board Games of a certain type often have this problem, where learning the game involves learning a particular shorthand for how to talk about the game. But while such jargon is useful to players of the game, it does tend to isolate the conversations from those not playing the game. All games have this to some extent, but my observation was that 4e had it far more than BX, ADnD or 3e. I think, and this is just my opinion again, that this was largely due to how the rules were presented in the rule books.
My second observation was that there was a difference in how 4e players tended to describe their games. I know, and you don't have to convince me that it is so, that it is possible for 4e players to talk about the game from a story aspect. I have seen it done and believe it can be done. But my personal observation was that this was not the typical way for 4e players to discuss the game. Most often they seemed to me to be discussing it from a more mechanical or gamist perspective. Again, I think this is simply the nature of the system lending itself to a particular sort of viewpoint and I see it all the time with boardgames. Its not a bad thing, it merely is what it is.
But I am still glad I have an easier time talking with 5e players about their game.
This is all very well said, or at least resonates with my thoughts and experience. Actually, I found this thread because I was going to start a thread about my own first impressions of running 5E, which in many ways are similar to yours. Will get to that in a bit.
