Great title that doesn't quite match up to the original. First major issue is that getting the true ending is borderline impossible without a guide. Second issue is that characters feel more one note and anime-tropey compared to the first game, even if they're still likable. Third issue is that the added content doesn't change depending on ending like the first game, just assuming you got the true ending.
Gameplay wise, however, the game is great. It's basically the same as 1 but with more moves, demons and characters to mess around with, making team building super fun. The story, while not matching up to the original game, is a unique premise detailing a more capitalism vs communism narrative instead of the usual SMT God v Lucifer one, and explores the concept well.
Overall, while not as good as the original, it's still a great sequel you should check out
