K, so I beat it.
Took 14 hours, on easy, which is kinda short.
But that was on easy mode.
But I powered my character the fuck up.
Sadly, the story tapered off a little towards the end, and so did the action, kinda. I mean, it was still really fun and sweet all the way to the end, but I think they could have worked on the story a little more.
The last battle was pretty intense.
So yeah, I'd say it's a 9/10 or maybe a 8.5/10. Solid game, great action, good voice acting, highly entertaining, but some complaints about story and shit like that.
The character development is pretty cool, though, and the characters themselves and incredibly deep, even the ones that you only encounter for a quick ranking fight. In that 10 or 15 minutes, you can really see character. No 2 dimensional characters, here!
At least it's not incredibly cheesey and lame like Devil May Cry 4.
