This is the type of answer I was looking for, thank you. I knew you get differing money or items, but I wasn't sure if XP differed depending on which course you chose. I suspected there are certain quests which you can block yourself off from by choosing certain dialogues along the way, therefore XP gain can be optimized by choosing certain dialogues and opening more quests.
It seems to me that some ways to resolve quests are much easier than others and it made me wonder if the "harder" paths and options you can take will give you higher experience rewards. Anyone know?
