Which was a good thing, because it's better when the producers follow the in-game canon, instead of when they try to create their own version of events. Since N was such an important character, he deserved a good backstory.It was great finding out about N's past too even tho it was very similar to his backstory from the games.
It's not like the Sages themselves had much importance in the games, anyway. So I get why they had a minor role in the anime as well.I was excited when the Seven Sages appeared, but then the following scenes came and I was disappointed. Too bad they will likely pass out with only that flashback as a cameo.
