The first DA2 playthrough was mages vs templars question at the end. It really was so difficult for my first Hawke :)

I can't really remember much of my first DAO playthrough but I really knew nothing about the world or the consequences.

I would say the one I usually struggle with now is how to deal with Gascard in DA2. There are so many outcomes and alternatives with different characters, and I'm also trying to roleplay it with each Hawke without getting too meta.
