Looking for new stealth games to play

I'm looking for stealth games that are more stealth than action, like the earlier Splinter Cell and Metal Gear Solid games, which are both in my Top 5 favorite franchises. I don't want an action game with stealth elements, I want a game where stealth is the primary focus. I had fun with the Aragami series, and Assassin's Creed until Origins was enjoyable. Any recommendations would be greatly appreciated.
