In Baldur's Gate saga, there is many times when some NPC walks towards you and starts conversation. But, there is small difference between how it worked in BG1 and BG2
In BG1, you immediatly knew if some NPC has some kind of buisness with you because they were making some kind of sound ("Heya, it's me Imoen!", "Hi friend"), while in BG2 you do not. Example:
In pure BG1, Tarnesh at the friendly Amn inn, he shouts "Hi friend" while walking towards you. In BGT or TuTu (generally BG2 engine), he walks, then after initalizing dialouge he says "Hi friend".
What I ask for is to restore BG1 method of initalizing dialouges. It just feel better. You know when someone has some kind of buisness with you, while in BG2 engine it was unexpected, and sometimes annoying (dialogue starts, while NPC starts saying something that's unrelated to actual text.
I hope I wrote it all in clearly and understandable way.
