If you start playing as a player in a homebrew world that I built. How little information would you feel needed to be able read before you can build a character in it?
I mean, nothing. I'll just assume standard fantasy tropes exist somewhere, keep my pitch brief and anywhere I need proper names you'll get or whatever.
It's not ideal but I've done it plenty of times.
Not to mention would you as a player like reference to other mediums so you could quickly know what to expect or would you rather have a in game view of it?
Comparisons with other media can be a powerful shorthand, but reference the wrong things and it can be extremely off-putting. Over the years I've learned that DMs referencing some media, even things I like, can be a massive red flag. Nothing triggers my flight instinct from a game quicker than seeing the advert reference anime.
