There are a couple of things going on in the world of D&D, both on a personal level, and the world at large.
First off, I just started DMing again after a nice 6 month break. My group decided they wanted to play some good old fashion AD&D 1E. This game has been out of print since 1991, and has been out of favor longer than that. The core 3 players all said this was what they wanted to play, they said they were tired of bonus actions, reactions, feats and weird combinations of multiclassing that breaks the game. Back then there was not a lot of options, characters were not differentiated by their race, class, or attributes, but rather how the player played that character.It did not matter if you were a fighter with a Strength of 13 or 18, what mattered is what you did and what you contributed to the game.
The other thing that is slipping in, is The makers of D&D, Wizards of the Coast (WotC) has decided it is going to change the game to add more diversity by eliminating all evil races, not really eliminating them, but rather make races like orcs and drow just as morally and culturally complex as other peoples, meaning they will no longer be culturally evil. A lot of people are upset about this, you know because why not. Personally, I say play the game you want to play and don't worry about what WotC or anyone else wants. The bottom line is, this is our game, sure they publish the rules, but we are the ones who bring it to life. Really, it is not a big deal.
