@lain The original Legend of Zelda was built for a world where kids would exchange information, show each other how to progress, buy magasines and or guides, or call Nintendo's hotline for help to finish it, and still feel the satisfaction of having beat the game. At the very least, you need to draw maps and be willing to do tedious trial and error to beat it truly on your own.
Gamers nowaday don't tolerate that, they expect a game they can beat with no external help, and no external tool (which is to say, no taking pen and paper maps, if manual map making is expected then at least gamers expect the tool to be inside the game).
I'll be honest, there's so many free (legally, gray area or not) or cheap games any friction, be it as simple as getting a pen and some graph paper, is a tough ask now.
