I really don't see anyone advocating that they should go full on Mecha and Sailor Moon with the Ki Power source. All Cadfan is discussing is Anime Tropes. He listed several of them: Less armored fighter, unarmed melee class, unarmed/magical class, eastern weapons, refocus mid-combat, and building on Second Wind for further mid-combat recoveries.
So I don't get "Some anime (namely the far-flung or Sci FI anime) doesn't work for d20, so all anime should be segregated to its own RPG and not allowed in the room with D&D."
Princess Mononoke, Ninja Scroll, Basilisk, Berzerk, Scrapped Princess - very easy to facilitate with D&D.
It's like saying "3e D&D does not facilitate low-magic games because of the necessity of magical items and magical healing. Therefore, low magic games have no place in D&D and should be in its own RPG."
Here, I'll show you what is being talked about. Here's an example of something Anime/Wuxiash that can facilitate in D&D:
Quivering Palm * Monk Attack 25
Daily * Unarmed, Ki
Standard Action * Melee
Target: One creature
Attack: Wisdom vs. Fortitude
Hit: 1d[Unarmed]+Wis damage, and target is weakened. Until the end of the encounter, or five minutes, you can decide when the Quivering Palm's effect occurs, as a free action. Target takes 3d[Unarmed] damage and is no longer weakened.
The problem is when some hear anime, either in bad or good when relating to D&D, they want/think it all, from DBZ super saiyans, to Karas, from Tranzor Z to Gundam.... It really doesn't all fit, and even some of the things people try to classify as anime based are really not, and just happen to be oriental such as the mythology. Like your quivering palm is real, not something just from anime. So maybe by not classifying it wrong may help go over, as I also like monk concepts, but not so close to say Kantarou from Tactics....
People will buy anything called D&D in epic numbers because what people want is something called D&D that they can play with their friends.
This will be true almost regardless of what the contents between the pages are.
Almost, because if they replaced it with FATAL, sure, sales might drop.
I bet it'd still sell a boatload of Core Books that broke sales records and demanded fifth printings, though.![]()
I do not disagree that a majority play D&D just for the name and all that comes with it from those of us through the decades that played it and made it grow to what it has become. I am pretty sure most new players get attracted solely for the name, and likewise it is the very name that may turn many others away.
I really think that some do want anything from D&D, so long as it has D&D written on it.

Considering that this thread asks "What do you WANT", criticizing someone for saying what they want really isn't fair. The OP asked for the answer that was given.
Yes, thanks for specifically stating what you want and feel D&D has left out for your fun, no matter what myself or others may disagree with you on. (like heavy anime influence)
Maybe somewhere in the future it will help someone see what is the correct course of action for making something for everyone, be it the amalgam game of everything inclusive, or seperate games for specific things.
