Is there other gameplay info besides the footage? Because all the footage seems to tell us is "this is SMT"?
Everything looks Nocturne to me, but probably because I haven't played the others.
There's a few things that i got from the Gameplay:
> 4 Apocalypse's Affinities are back, aka Ice demon use Ice magic better (stronger , less mp cost , etc) than Fire demon and vice-verse. Same apply to Buff/Debuff, Almighty skills , Ailemnts, etc.
> SMT 1 , 2, If , Nocturne , etc Moon Phase mechanic is back
> Magatushi from Nocturne seems to be back and seems to work as a Limit Break mechanic. Your MC has power that needs to use Magatushi as resource
> No Random Encounters, instead it goes for the SMT4 and 4A of in world enemies , but now full render instead of hologram.
> If MC dies , it's Game over , like Nocturne or Vanilla strange journey.
> There's no Gun , only Physical this time around, also Physicial sadly costs MP instead of HP to use (RIP Physical demons). Fire , Ice, Wind , Eletric , Light and Dark are back too. There's a ''Miracle'' tab when you level up , no clue that means. Maybe it's the way to get new skills similar to Nocturne's Magatama.
> Vitality is back. Oh Guard is also back from SMT 1 , 2 , IF and Strange Journey.
The rest is typical SMT stuff.
