7 years later and I still can't get passedin the original Etrian Odyssey. My characters are already max leveled and yet it's still incredibly difficult.the sixth stratum
Well, you made it farther than me.
However, I did tooth-and-claw my way through there on Expert mode in Untold. That place is hell. Toughest final stratum in the series IMO (well, III's is really nasty, too).
In short: your Mega Drive-style music.
In "long":
Thanks for the details. Didn't have room to go over music in OP.
Personally I like both styles and think the music in IV and Untold is really great but it is still certainly different from what the series had before.
