I didn't need 1E, 2E, 3E or 4E to achieve that goal either.
I agree. That's my point. Our group is our group. And, what game we play depends on the group. The group isn't beholden to what game we play.
If we all agree to play Game X and that game doesn't have Encounter Powerz, I'm expecting that we already discussed that with Bob and he pitched Game Y with Encounter Powerz but the rest of us didn't want to play it.
Now granted, I'm pretty open to playing any game, so maybe next time we play Game Y.
And yet some people consider them to be important enough to them to write-off wholesale any game that contains them.
Yeah, that's pretty silly.
I used that as an in-thread example. A group always has to find a game that they will enjoy. And I usually don't find the people in sit across the table from on Friday nights to be as divisive as people on the internet. There may be aspects of the game that don't make sense to them or that they don't like. But they still play because we are friends and they enjoy the games I run.
Right.
So, my point is, there are groups out there right now playing 1E, 2E, 3E, 4E, Pathfinder, Indie Games, etc.
And, WotC is like, "Hey, we got this game 5E that you can all play, just switch out the options!"
Those people aren't just going to switch just to switch. The game needs to be based on the same principles and do what their current game does, but better.
Now, not only does 5E have to do 1E better, but it has to do 4E better.
And, that has more to do with the overall feel than whether the game has a Tome of Battle splatbook for the 4E fans and Vancian casting for the 1E fans. The whole core of the game, it's design and presentation and ideology has to be right. You're talking about 30+ years of varying playstyles.
Hell, just yesterday there was someone trying to tell me that the Dungeon Master Guide for 5E shouldn't have guidelines for building
dungeons.

Wtf? What that person wants out of D&D is
vastly different than what I want out of D&D.
I'm not saying it can't work. I have high hopes it will. I'm just curious to see how they do it.
