Apparently you are the dense one, since you can't seem to grasp that i'm only sticking to that one RPG element that you want introducerede into the series. Conversations with multi-option dialog parts, i don't like RPG games and i don't want any classic RPG elements in Hitman. The multiple option conversation feature only makes sense if there are different outcomes to the dialog. That is why they exist in RPGs.
I don't mind other ways of getting more intel on targets, but i don't think conversations is the right way to go about this. Because these kind of features are designed for other kind og gameplay mechanics, like character personal development, allegiances, hidden benefits, classic RPG world building.
To me it seems like unnecessary filler for something Hitman already had. Like 47 talking to the hotel manager in 'Tradition of the Trade' and learning that his "friend" Mister Wolf is staying in room 202 or talking to the Bartender in 'You Better Watch Out' gives you intel that you use to isolate Chad Bingham, Jr. To me adding more optional dialog parts seems like a waste. Then i rather want more NPC to interact with then a more fleshed out Conversation system.
Okay name some of those games. Because i don't know any of them, but if it's an RPG like Deus Ex, Witcher, Mass Effect, SW Kotor...then all these it's part of the character development and world building.
Personally i don't like these mechanics in Action Adventure/Stealth games, because there are very few RPGs that i like. I'm not a fan of Role Playing games.
