You are the one who brought up Appendix N. That suggests that you have a list of books you consider "D&D Feel". But the list you gave us - Appendix N - is extremely dated. All I did was suggest that you include in the discussion some more current materials that you think would receive your "D&D Feel" stamp of approval.
If, on the other hand, your intent is just to troll the thread, then it would not be necessary for you to actually contribute to the discussion.
In actuality, D&D has a fairly long lifespan for its editions.And all that wonderful "improvement" in 4e has brought us right where we are today. If all that improvement was so good why are we looking at a new edition of the game in record time? All the changes were NOT for the better and the edition failed. The facts speak for themselves, but you can't hear it if you refuse to listen.
Actually I began playing 1e in 1980. Eventually trying to houserule 1e into something I was satisfied nearly drove me to madness. I was relieved when 2e came out but it didn't fix many of the things I didn't like with 1e, plus sanitizing the game for Mothers Against D&D was a colossal cop-out. I liked the changes that 3e made to the game, but then they went and added tons of superstructure to the game I DIDN'T like.
Pathfinder came out with their "fixes" to 3.X but went in the direction of increasing the complexity when I was hoping for decreasing it. I love Paizo as a company, but their rules system just didn't appeal to me. 4e was never a game I could warm up to. It may be an excellent miniatures Skirmish game, but it threw out way too much of the things I liked in ALL previous editions. I do like the rule on critical hits though, so there is that. Castles & Crusades came the closest to "being D&D to me" so that was what I went with. But, since it didn't have the D&D logo on it, it never received much traction in the gaming world. The publisher's habits of poor editing didn't help either.
5E now comes along with a stated goal of creating a simpler, modular core that can be extended with expansions. So far this sounds like a wonderful design philosophy. The designers are also making a huge effort to promote the game in terms that are as inclusive as possible. I absolutely applaud this.
What they have said gives me more hope that 5e will be the best version of D&D that I have ever laid eyes on, even games that don't have those three symbols on the box. Now when the playtest rules come out I may find myself to be completely wrong but I don't think so. I really think I'll like at least 90% of the game and if they get that close I will be elated.
When the final rules are published I would love to be playing and running actual D&D again. At least at this point I have hope.
No, that was me recognizing that my entire rant is really one big "No True Scotsman" fallacy. That it is one doesn't particularly bother me since this is largely just a question of differing tastes,You write up all this and then tell us that WE are the ones playing a no-true-scotsman fallacy? Gimme a break.
If the new edition is to truly consolidate editions, then they should be in the first PHB. It's not truly consolidating editions if they don't.If the new edition is to consolidate editions, then tieflings and dragonborn don't need to be in the PHB, since they only made it into the 4e PHB.
