I'd say another con for MGR is that it arbitrarily blocks off areas when you get into battles sometimes. The best part of the entire demo is when you're in that huge area with all the soldiers and Gekkos, and it let's you just move around the area in a lot of ways. but then a lot of other encounters have you in this battle fence, and it's sorta disheartening. It was a very silly holdover from DMC/Bayonetta that Platinum shouldn't have implemented, I feel. To me, MGR still feels a lot like a Metal Gear game, and inexplicably closer to playing as the Cyborg Ninja in VR Missions, but with that Platinum games flair to it. It's not really the best "hack 'n' slash" because of how easy it is to take out a lot of different enemies.
Also MGR doesn't really have any sort of dodging ability (in the demo at least). The closest you get is hitting Square+X to a sidestepping or backstepping slash, and it's not all that reliable :S The parrying is cool, but...sometimes you just wanna get the hell outta there, and Ninja Run just doesn't do the trick sometimes. Hopefully there's an upgrade in the full game for dodging.
I also find it sorta funny that people say DmC is really casualized and that MGR will be so much better, but MGR has a lot of the things people feared DmC would have (like QTEs), and MGR is so user-friendly that every single enemy attack comes with a nice glowing broadcast >_< DmC has it too, but...still...
It is kinda nice in DmC's narrative because now he has Kat with him a lot of the time, so there's some good exchanges throughout gameplay; "Dante! RUN!" "I AM running!" Even when Kat's not around they still find a way to have Dante interact with people, like responding to Lilith's Devil Has Talent stuff with "I don't have time for this bullshit!" or even just saying random quips to the demons during fights, "C'mon down guys! Let's get violent!" So far MGR's in-game talking likes to wrest control from you with that Vanquish-style walk-and-talk radio stuff, which I think sorta breaks the flow a bit :s
I'm still excited for both, as they fill to different action game desires, but I'm still more excited for DmC because of it's overall combat and such.
