Debatable. I know a bunch of guys who really like the game, but I can't really get into it.
I love ArcSys, the company that made DBFZ as well as Guilty Gear and BlazBlue, but there's a few things I can't really get over. Most importantly, I don't really like team fighting games. I think like 2v2 is alright, but 3v3 isn't for me. The game compared to the fighting game I usually play, Guilty Gear, has very few options, both offensive and defensive imo. To me it feels like a lack of freedom, not having those options.
There's also some minor, not really gameplay related things like the forced lobby system annoys me personally. I'd still prefer a menu where I can just go into Training mode right away, instead of having to load in some lobby first and walk there. For online play the lobby thing is alright, even though I also prefer GG's approach to that as well.
Not my type of game. I'm actually waiting for BlazBlue: Cross Tag Battle right now, in terms of new fighting games. Until then I'll stick with Guilty Gear.
