Game drags on for 60 hours before it gets remotely difficult. Then they introduce their secret weapon: an insanely long cutscene literally around every corner. Finally, the difficulty spike in the 'finale' chapter makes you want to quit.
I wouldn't recommend this game unless you're a die-hard.
Also: Mini games are bad, picture collect-athon, friendship collect-athon, kiryu memoirs collect-athon, fortune collect-athon, aloha-friends collect-athon, music CD collect-athon, Sujimon collect-athon, I probably missed half a dozen other collect-athons.
