Well, the LN/manga I mentioned is the only one with a somewhat similar premise that I'm aware of, but I'm not surprised if this is really a pretty common trope. Isekais quite often rely on reusing ideas from the earlier works over and over again, to the point that often nobody even knows who came up with that idea originally. On the other hand, many authors still manage to make creative and/or genuinely well written works using these tropes. This game is most likely neither of these.
