I don't understand what you said but I get the gist of what you mean.
Fable = What your actions do. Mass Effect = How you put something.
Those are my 2 favorite RPG's, Fable taught me a valuble lesson when I was younger and it's amazing how much of an (awesome) influence it had on me. Mass Effect 2 - that helped a lot as I opened up and saw that the way he put it was quite realistic and I might as well give it a shot, it really does help .
P.S World of WarCraft as well but I don't class it as an RPG lol :>
Well my favorite one was in Warcraft 3 frozen throne on B.net a custom one called Twilight but I stopped playing it after they updated it And ruined it :P
