honestly, this is fine. I think people within the rpg space forget that the general public largely has no idea that the space exists. they have never heard the term “tabletop role-playing game,” but they have a vague impression that “d&d” means nerds sitting around rolling dice and pretending to be in a fictional scenario, so if your game is anything like that, “kinda like d&d” is a fine descriptor for that audience

or as the famous tweet says: “guy who’s only ever seen Boss Baby watching a second movie: kinda getting Boss Baby vibes.” inaccurate or ridiculous as it may seem, if that’s the only exposure someone has to the concept of a “movie,” then using that as a jumping-off point to explain that other stories of different types can be told by pre-recorded moving images is still useful. you have to introduce the medium in general before worrying about genres within the medium, or works within the genre
