I'm playing Two Worlds Two again. I play it every couple years. I just really enjoy the crafting and magic systems in these games so much and the story is pretty good too.
Basically any weapon, armor, clothing, etc can be broken down to its base components. You can then take those components and improve another item. There are wood, iron, steel, cloth, etc and then there are gems that can be socketed into the crafted piece that will add stats or skills. It isn't as varied as a Diablo, but it is quite cool for a full-fledged crpg.
Spells are formed from several cards that you place in a carrier. The cards can be quite varied and Two Worlds probably has more spell combinations than any other game out there.
I also love the loot system as there are just tons of chests to open, locks to pick, traps to avoid, etc. It's just a great game. If you haven't played it, you're missing out. It is older now but still looks pretty good for a 1st person game. There are some video tweaks that will get it up to snuff fairly quickly.
Once I get my 2W2 fix, I'll probably go back to Diablo 3 and Grim Dawn again. I haven't exhausted my fun from either of those yet.
