i would say mass effect as well, shepard is what i call a rather immersive blank template character. not that you have that many roleplays choices with it, but there is still enough granularity in its binary choices that lets you develop somehwta a rather interesting character.
You have exactly two choices in each conversation, be Jesus reincarnate or be a street thug and smash face. And ofc you can flip flop between the two for every conversation because "roleplaying". If anything,
ME is the perfect example why open character creation will never lead to great characterization. The only thing that made Sheppard appear to have actual character was the excellent voice acting (with fem sheppard at least).
An ultimately flawed but funny and interesting appraoch I've seen to remedy this dilemma was in Divinity Original Sin. You are making two main characters and they can argue with each other on how to respond to moral choices. It was clearly meant for coop mode, but even in single player you can argue with yourself and see how the arguments play out. At least that's a new idea. Still only binary choices sadly.
