I am enjoying this game a lot- Purchased at launch and still find myself playing it. The single player mode is very well done like an RPG with more of a fighting-game approach to the combat system. But after playing .hack//G.U. and CyberConnect2's other games... Well, they set the bar pretty high for themselves.
I still find myself playing it because of the multiplayer, while honestly the core of the game isn't that deep or complex in comparison to an honest fighting game (Street Fighter 4, Marvel 3, etc.) that's what I like about it- That's what makes it fun. It's a casual fighting game that doesn't take much to play at a high level. You don't need to practice the game for months and months to play against good players. Well worth the $60 price tag but nowadays it's about $30 for a new copy. Even if you don't like Naruto, or fighting games... It's a great addition to any 360 or PS3 library.
