First off, I don't wanna hear people saying there are no SMT or FE elements in the game. If you watch the trailer closely you can find a LOT.

Also, thanks to Hiku for sharing this. - v

"In this PV, many people may find it hard to understand where the essence of “Fire Emblem” comes into play. However, this will be explained more in the future, so please wait for a follow-up to this."

Second, there ARE Fire Emblem characters. Tiki (a known FE character) is shown in many instances (at 54 seconds in the trailer there is a poster of her as well.)

They are using the class system from Fire Emblem (proved by the archers/Pegasus knights)

Now for SMT elements, the battle system seems to work like SMT but using the characters with their classes instead. (demons are also shown in multiple instances) Also, you only control the main character from what we have seen and that is all you get to do in an SMT game.

Now, Persona is definitely influenced, but I have a feeling the game will start out happy and go getting and then get darker as the story progresses. I mean look at the ruined city near the end of the trailer? That's what SMT is all about. Atlus is most likely hiding this and waiting until E3 for more details on the story. So, they will most likely start out in a normal life with that cool other fantasy world thing they have for fun experience, but then everything goes to shit cause of gods and stuff. (also again, supported by the ruined city)

What are your thoughts?

What FE elements I can find if I watch the trailer closely? Other than (obviously) FE characters.

It looks better than I thought it would be. It seems alike a lot of work is being put into the game. I thought it was going to be a low/mid-budget SRPG with characters from various fire-emblem/SMT games (something like Project X Zone.)

Read my OP.

Yeah I think a lot of people expected that. But it's something no one was anticipating and it makes me more excited honestly.

The game looks to be the #1 Waifu simulator of 2015 (at least in Japan T_T)

Well, other than FE characters and what might or might not be the class system from FE because that could as well just be the Persona summoned.

I think I can pick out a few FE characters such as Caeda, but the different design isn't what I was expecting at all. Not that it is bad, but in fact, since it looks like Persona 5, I'm actually a bit more excited for this game!

It took some time for a teaser, but now that it is out, I sort of know what to expect so the hype can begin!

I know I spotted Chrom, Lucina, Tiki and I believe a couple characters from the next Fire Emblem.

Thing is, it doesn't look like what I pictured at all. Way too Japanese/glossy for my taste.

That is no doubt the class system. They wouldn't have a crossover between these two franchises and then just use elements from two of their franchise.
