Played it a few days ago. As a action game in itself it's competent, the weapons are ok (the glaves are my favorite along with rebellion) and the platforming is pretty good at times ('ll get back to this later). I've also noticed that there's not a single QTE in this game, which I found strange considering 1) it's a modern AAA title and 2) the last two Ninja Theory games had a significant amount of QTE's. It was refreshing to say the least. The visuals were at times very striking, especially for an Unreal Engine game (played the 360 version) the shifting environments of limbo were very cool the level design was varied and always threw something new at you.
Now for the negatives. The lack of a manual lock on really bothered me and it got frustrating trying to get that flying enemy that was hitting you offscreen at times. Why Ninja Theory decided to omit it is beyond me. The camera isn't totally good and can get in the way of platforming, which can get very repetitive itself towards the end. The style meter is broken to a point where you can get an SSS ranking with one hand, on DMD. The music is generic WUBstep that gets blasted through your ears in attempt to murder the eardrums, unless your into that sorta thing.
Now time to unleash my inner Devil May Cry fanboy on the game. *unlocks cage*
I hate Dante's character in this game, no it's not just the hair, it's the character in general. He's a complete unlikeable dickwad that only 14 year old One Direction and Justin Bieber fangirls will get moist over. While the old Dante was also a cocky dickwad at least he never go around screaming FUCK YOU to everyone. As for Vergil, I like his design (nice homage to his unused DMC1 model) but unlike his old counterpart, he has no sense of honor and would make some very out of character decisions (If you played the game you know the part im talking about). There's even a point in the game where I felt sorry for the bad guy and was rooting for him to smack Dante's shit. When I have to root for the bad guy in opposed to the heroes of the game, you did something wrong. The combat, while competent, pales in comparison to the previous games and being locked at 30 fps really hurts it, thankfully we have the PC version to scratch that 60 fps itch.
Overall I think the game is good on it's own, it's not 1.0 out of 10 bad like everyone makes it out to be, if anying it's more of a 7 out of 10. If your a hardcore Devil May Cry fanboy you will be disappointed that it doesn't stack up to it's previous games but it's still a decent action game worthy of a rent at least. I just hope that Ninja Theory improves on all the problems DmC suffered from in the sequel (we know it's happening since the core Devil May Cry team is busy working on Dragons Dogma 2.)
