I arrived in the first city and there is so much speaking from the NPCs. I noticed that each NPC repeats his line at every 20-30sec. If there are 3 NPCs talking that means that almost all the time an NPC is speaking, and many times two at the same time. It's very hard to read the dialog when somebody is always talking, its very distracting and annoying.
If you legally bought the game just patch it to the latest patch, it fixes the contant NPC talk.
If you are using a certain version of the game that was "released" ilegally than yeah, the constant NPC chatter is not patched yet.
As i'm sure you got the legal version, right ? Patch it then, it's fixed already.
