Yep that bar is not hit yet.The bar would be too high, wouldn't it? And there will be no answer to that question.
Even if we take the bad RPG Skyrim as the criteria, we barely have answers to the title's question. Which kinda shows just how bad the RPG situation is nowadays.
I love Witcher 3, KCD and RDR2 - all three my games of generation - but in pure roleplaying complexity and player agency, New Vegas still rules (in AAA sphere, not talking about isometric games).
I think New Vegas was a low budget tittle compared to something like Fallout 3/Skyrim. I'd say in recent times Kingdom Come Deliverance offers a lot of freedom and it's a mid tier tittle budget wise. Apart from that, nope there aren't any.
Unless you count low budget titles like Divinity Original Sin 2, which despite being so cheap come across as AAA and offer an absurd amount of freedom.
Yep!
