The demon doors in 'Fable' games are such a fascinating part of the series! Once you’ve opened one, it stays accessible for the rest of your playthrough, which is great because some of them hide unique rewards or quirky challenges. I love how each door has its own personality—like the one that demands you be ugly or the one that asks for a specific outfit. After unlocking them, you can revisit anytime to admire their design or grab missed loot. It’s a small detail, but it adds so much charm to the world. I’ve spent hours just messing around with their requirements, and the fact that they remain open makes exploration feel rewarding.
One thing I wish the games did better, though, is hinting at some of the more obscure requirements. Like that door in 'Fable II' that only opens if you’re in a relationship—took me forever to figure that out! But overall, the permanence of opened demon doors encourages revisiting areas later, especially if you’ve leveled up or found new gear. It’s a nice way to keep older zones relevant.
