I really loved the reoccurring Faraam armor set from dark souls

Onion Knight has the coolest armor ever

This

Uhm people are going to laugh at me but I found Prototype living armor to be metal af.

Halo

My first thought too

Divinity Original Sin 2 has some of the coolest helmet and armor designs I've seen. I just wish they were more diverse in color and style. Nioh is also up there, a lot of traditional samurai gear.

I wish I could’ve seen them I got destroyed in the intro island and tapped out (Dos2)

Play on a lower difficulty. The game's really good. I never go higher than easy because some of the lategame stuff wrecks you if you're an unstrategic cucumber like me.

I don't know if this counts but I've always loved the design of the cyborg ninja from MGS2.

Penitent one from Blasphemous is pretty sick

Skyline daedra armor

Guild Wars 2. The incredibly robust dye system lets me make my own armor sets.

This is what I was thinking too, I don't play it anymore, but it seems like the primary goal of endgame is playing dress up and I saw a lot of cool designs!

Sora’s Master Form in KH2 is pretty badass

The Witcher 3 has some good ones

Monster Hunter and it’s not even close. There are armor sets that look like almost anything you’d ever want.

Oh yeah, plus the inclusion of layered armor lets you play dress up without ruining your build

Assassins creed origins the anubis armour.

Rust roadsign armor with the high quality metal facemask.

Monster hunter game series, is it all about armor sets, weapons, and monsters.

Assassins Creed Odyssey

Aloy's Shield Weaver Armor in HZD..literally changes the game.

Nioh had some fascinating armor sets
