RAI was overhyped. Personally I think clever scripting can do a better job of it. I mean, I enjoyed watching a guy pickpocket someone else and get killed by a guard. And yet, should he have done it with the guard right there? Should the guard have killed him over a piece of cheese?
I just want a better interaction system, ie, being able to tell every NPC simple commands whose success is based on disposition. And a better disposition system. If I bribe a guy 10 gold, he might tell me a secret, once. If I give him 100 gold, he might help me kill someone. And although his Disposition raised enough to help me kill someone that day, it would fall back down. It would be a LITTLE higher, cause he knows I got the cash. But there's a "what have you done for me lately" necessity. But while bribed loyalty is short lived, the kind earned through friendship or affiliation would be more permanent.
