I can get with that. The only game that felt like stealing and stealthing was satisfying was Thief for me. Most times thievery feels kind of gimmicky (the pickpocketing and such primarily) and tends to be more hassle than it's worth. So many RPGs tend to put thieves in the assassin style role by default where they can sneak up and get an insane backstab critical but don't really explore many things that would make them a thief.
The assassin style is "okay" but it feels like an easy way out for a class that can offer a totally different playstyle in and out of combat. I understand why they do it though since it'd be tons of work to really try and nail the feel of.
Personally, I liked Kingdom Come Deliverance's approach to stealing skills such as lockpicking and pickpocketing. It's probably my favourite in-game interpretation in quite a long time come to think of it.
Thieving was great in Skyrim as well. People who only play sword+shield characters and screamed "Skyrim combat suuuuuuucks" never figured out, but Skyrim has actually a great stealth implementation. Light matters, positioning matters, sound matters, positioning of sound matters. Exactly like Thief... Playing a stealthy thief/assassin with daggers only (get away from here, you stealth archer faggots, daggers or bust) is one of the most enjoyable steatlh experiences ever, in any game.
