What changes were made to the dialog in BGII:SoA?
Dialog is still based on selecting choices, but has been made more complex. We have broken dialogs into smaller pieces, normally 2-3 sentences, giving you greater chance to affect its course and cutting down on non-essential material. The leader and reputation will also have greater affect on conversations. While you are talking, one of your NPCs might take part to the conversation and let you hear his/her opinion.
