It's really fun so far (I''m early in Tokyo, which I feel is where a bulk of the game happens). You can save anywhere which makes it a bit easier (otherwise when you die you have to give a ton of cash to Charon, it's faster to just reset the game), but the game will still kick your ass from time to time. It does everything I feel the Persona series ignores (like actual exploration and not reading for 90% of the game), and it does a lot of really fun stuff with the scouting of demons and such.
I'm having lots of fun with it.
