Yeah, that’s the part that confused me. Skyrim’s enchantment system is just it’s enchantment system. It’s not as… exclusive as Fallout 4’s legendary system. I think that’s what makes it distinct in my mind. I definitely see what you mean.

a deathclaw is a deathclaw.

Fallout 3, sure, but with New Vegas? Not really. There’s plenty of places you can go and then decide whether you’re making friends or enemies. You can interact with them, and then decide if you want them dead or not. There’s definitely some places where- like you said- a deathclaw is a deathclaw, but there’s also plenty of exceptions.
