Considering that Awakening was going to be the last Fire Emblem game if it didn't sell well the team behind it really just went, "What can we do to assure it sells?"
The answer was throw as much nostalgia at it that could fit. So anything that has ANYTHING to do with another entry in the series is most likely pure nostalgia.
Yeah, that sounds right. Calling back to the older games just helped audiences make a connection to the older games.
Okay, everyone ship Alm and Celica. It's probably the only way to get their wedding.
Think the units will have kids? Wouldn't it be funny if Sonia and Python had a child?
List, and the artists will have a lot of work to do redesigning all of them.
That opening video with them as children was so cute that I'm absolutely going to be shipping them.
I'm not sure if they'll have kids. As much as I like how Awakening and Fates did that, that might require too much of a change to Gaiden, and considering how kids are the result of S supports, it depends entirely on how the support system works.
The artists definitely have a lot of work to do, but judging by what we've seen so far, they've done a decent job of making them recognizably close to the original character while heavily updating them.
