I've seen a question on Miiverse asking about how having both games as physical copies would affect your gameplay in any way. Such as anyone being able to access a "Branch of Fate" from Conquest while having beaten the game on Birthright, or vice-versa. In that discussion linked in the URL seen here, I see someone saying that it's possible. But is it really? As soon as I saw that statement, this has been kinda bugging me.
Any insight on whether anything would carry over from physical copies or not?
