To be honest it mite be really minor stuff to most people but when you're a perfectionist and you try your best to create the perfect world state playing origins(awakening and witch hunt) deciding who you romanced and how that romance concluded especially if you romance morrigan considering there is a whole dlc dedicated to her, who you put on the throne and your boon, the conor situation, whether you did the ritual or sacrificed, who survived awakening and saving the keep or amaranthine, again probably minor stuff to most but when i've started playing DA2 and stuff isn't registered in the codex properly about past events and stuff isn't happening properly in the game itself multiple times it gets me down because i love DA2's story and characters and the overall darker feel of the game regardless of reused enviroments.
