The Okumura arc made me drop the game for 4 months.
Aside from the barely existent difficulty of the game, I don't really have any complaints, it expands on Vanilla P5 perfectly and gave us probably the best final villain in the entire series.
Great music, great gameplay, great visuals. I would also like to mention that Atlus actually did a good job with the port, which is a rare occurence unfortunately.
