Is Atlus even working on EO5, because I haven't heard from it in forever. I have a feeling they're just focusing on P5 at this point. Also, sorry for the low quality pic. Maybe we can share high def EO images.
4 is easy.
Untold is hard with a setting for easy.
4 however, has the Sky. The sky is amazing. Not as amazing as the sea from Etrian Odyssey 3, but still good.
PERSONALLY? I like 4, though it lacks a seriously difficult endgame. Untold and Untold 2 have a shit ton of postgame stuff to do.
I personally prefer IV above all of them. Subclassing is fun and the overworld is made a whole lot better than III. Grimoire stones have always been annoying to deal with, which is in Untold and Untold 2.
Gameplay? Probably 4. The game got SERIOUSLY fun around Stratum 3.
Untold 2 is rather stable, for better or worse.
But the stratae in 4 are seriously small. 3 floors per dungeon, the dungeons do not (usually) connect, and they usually dont take up the whole screen either.
4 is easier, but more fun.
Shit, I enjoyed that Untold was somewhat hard, and that it had a lot of postgame, but IV sounds kinda more fun than UII.
Fuck it, UII it is, I can't really go wrong

Untold 1 and 2: Refer to 1 and 2.
