No, but you do need *a* common language.
You yourself said it: when there is no D&D, there is some other dominant game, or at most a limited number of dominant games. I do not argue for D&D specifically, i'm saying that the rise of a dominant game, or few dominant games, is unavoidable.
and yet, the indie community lacks players for anything specific. the community for a game is made of 30 people worldwide. I speak from experience, having been part of some such community. And yes, some of it is nice, but at the same time it's missing several advantages of a larger community
what? are we even playing the same game?If you're used to D&D you're used to games that are 600+ enormous pages long just to be able to get a sense of the system.
I can introduce new players with 30 minutes of exxplanations if they never played rpg. this cuts to 5-10 minutes if they have rpg experience. you don't need to memorize the spell list to be able to play.
And I m sure those games that have 1 page of rules are much more freeform. some people like them, some people don't. I, personally, don't like stuff to be too much of a game of "DM may I?". Technically, everything you do in rpg is DM may I, but you can have at least some framework. I do like that, if I want to go deep, I do have access to thousands of pages of content. it's what kept me from getting bored of the system.
