[Dark Age Iron Savior]

most importantly, the SNES version doesn't have the full version of the boss battle, Embassy, Shibuya or Cathedral themes (I believe these were all in IF, so you could probably patch them in). Although I think I prefer the rawer SNES samples to the PS1 instruments. It also features the Majin theme from SMT3 that is so hard to get out of your head.

On the other hand, it doesn't produce 800kb screenshots....are those straight captures?

the craziest shit I read the other day is that the improvements in the mobile version of Romancing SaGa II (which seems to generally be the best regarded in the SNES trilogy) were actually first included in the Virtual Console release as bug fixes and DLC. I gotta figure this out.

oh shit, SMT Imagine shut down. I really should've tried it while I had the chance...
Fuck.

Have you guy seen all the absolutely crazy mounts Imagine had:

But the best I've seen so far are Alice and Cu Chulainn:

Unless Atlus has specifically said that they are related, it's probably closer to what Persona said. I'm pretty sure the Amala Universe concept was introduced in SMT3 to deal with all the vague connections/similarities/easter eggs the games (and spin-off media) already had. The only non-mobile game which explicitly takes place in the same timeline as the original two SMT titles is IMAGINE, which supposedly happens at some point between them.

Other stuff that seems related is just similar parallel universes. The plot of the Raidou game hinges (at one point) on proximity to a set of events that closely resemble SMT I/II, and a sidequest in the second game implies that not only can people theoretically move through time or to parallel universes, but that demons also feel a connection to their existences in other dimensions, even potential ones that are not yet realized (I think). Come to think of it, that was actually probably related to how the archangels show up in DDS2, which initially seems like a boss cameo similar to the Demi-Fiend in DDS, but I feel is actually meant (along with the final dungeon/boss area) to hint to the player that the whole Law/Chaos conflict is a lot more complicated than the YHVH/Lucifer grudge match that the True Demon leads you to believe.

I feel like some of these things would be clearer if more games were translated - specifically Megami Tensei II/Kyuuyaku Megami Tensei and the first two Majin Tensei games (the former in order to better understand the nature of the Great Will, and the latter because, while Majin Tensei has a pretty barebones post-apocalypse plot similar to Megami Tensei II or the first SMT, Majin Tensei II apparently builds upon it while invoking both time travel and parallel universes).
