All sorts of things can be discerned from this footage, including movement ranges (which will likely carry over to the final build, given that it's out in a few short months), animations, map design, class nuance, sound effect quality, and Japanese vocals. Plus, we even get a look at some downtime and character dialogue! This latest batch includes a young-ish character voiced by Kohei Amazaki, described as a guardian who assists the divine dragon. We got a look at another guardian, voiced by Yoji Ueda, last week.
It'll be hard to top the tri-story nature of Three Houses for many fans (though I know there are people who will be happy to get back to basics), but I'm hopeful for Fire Emblem Engage. There's bits and pieces I dig so far, namely the idea of mining nostalgia; I just hope it's done well from a gameplay perspective.
