My friend, who let me play the fifth installment on his account, once expressed concern that it has the best combat system in the series, and going back to earlier games might not be as enjoyable. However, I suspect that if I hadn't played and thoroughly enjoyed the fifth game, I might have dropped the fourth game altogether. And it's not just about the combat itself – they aren't that different in principle, but the level design, even by 2008 standards, is very weak. If you think about it, you could even praise the developers for managing to create such a large-scale game despite the limited capabilities of the PlayStation 2 and, probably, the budget. But running through these levels doesn't become more interesting because of that. Another significant drawback is that there are too many ugly creatures, in my opinion, both those that were intentionally made caricatured and those that were simply unlucky due to the overall style of the portraits.
Nevertheless, despite the above, this game also has its strengths. For example, I liked the city more than in the fifth game – it's very cozy, and I would like to live in such a place. The detective storyline is also excellent. The characters... Well, I'll say that the group here seemed more friendly to me. I liked the idol, the detective, and the first ogre the most. The beautiful girl is nice, but her personality isn't quite right. Everything is very sad with the girl. The mascot initially annoyed me, but over time, I started to perceive him better – like a brother.
In short, I have very mixed feelings about this game. It didn't help that I was very emotionally and psychologically exhausted recently; it's quite possible that I would have enjoyed it much more in a different situation.
