[quote name='Bulrog']For the Journey, 40 to 50 hours is way too low. I've played through the journey twice and both times it took me over 80 hours. I mean trying to rush through the game I could imagine 70 hours maybe 65, but 50 is too quick.[/quote]
I can't really imagine doing everything on the first playthrough. There's something like 13-15 social links (I think I missed one completely on my first playthrough), as well as 3 social stats (Intelligence, Charm, Courage) to max out.
I barely managed to get 9 maxed links and maxed my stats by the end of my first playthrough, and something like level 83. Not to mention doing all the requests, getting all Personas (first playthrough I ended up with 75% or so), and getting awesome weapons via Persona weapon fusion. Luckily my second playthrough was a bit smoother, as I allowed myself to use a guide since there would be no spoilers.
I do wonder how long P4 will be though, since The Journey (1st playthrough) took me roughly 75 hours, and The Answer around 25.
