There's a weird effect where sometimes one game in a genre will become so iconic that nobody wants to try and make another one, possibly out of fear of seeming like they're ripping it off? It happened to Descent, and I feel like it happened to e.g. Myst as well - everyone was expecting the huge success of Myst to launch a whole genre, and then it just... didn't.
Myst may not have launched a genre, but it did establish its own kind of game style. 3D world. Adventure game mechanics, with problems and puzzles - but where progress opens up more puzzles, and where instead of developing the character skills, you develop the story. Slow paced. There have been plenty of games to tap into that style, but not enough or frequently enough to warrant calling them part of a genre. Black D…
7th guest came out first. Too dark, while also being too campy to have the widespread lasting appeal of Myst, so no surprise why outside a niche one is mostly forgotten and the other always comes up even if only to hate for some. But they were basically the same game.
I don’t even know if 7th guest was first of its kind, probably not, but it sold bucket loads, partly because it was a pack in game for MPC kits and PCs in the early 90s.
