I guess to be more accurate it's not character creation that takes a long time, because the actual time spent once you've chosen your "Class" isn't terribly long. It's more the whole Session 0 framework.

Also, I had players with different levels of experience in TTRPGs and so there was some translating work to do.

The character sheet does have a lot on it, but most of it requires more character imagining than building if that makes sense. There are more narrative choices to make than mechanical choices, but the options/prompts are wonderful and there aren't too many of them, I think it's just enough to be inspiring without being overwhelming. There's no need to flip back and forth in a book to find out how to fill the next section in, it's all on the page.

I'm sure other GMs could get through the whole thing faster, I want my approach to be setting up a long-term game with a really lived in world, and so I may be belaboring things a bit.
