I like the Devil May Cry series. 3 is by far my favorite with 4 in a close second.
1. You may enjoy the combat very much. But it gets dull much sooner than original ones. Also if you fan of good boss fights like me you WILL be disappointed.
2. Don't buy this game new. Because if you like this game apparently to Ninja Theory you have wrong sexual orientation: http://www.blogcdn.com/www.joystiq.com/media/2013/03/dante2.jpg
If you like DMC, you will not like DmC. If you think Knight's Contract is a good game, you will love DmC.
My question is does the gameplay outweigh the terrible dialogue and characters enough to constitute a buy as a DMC fan?
No. Besides feeling more in line with a GoW than a proper DMC with how slow and clumsy the combat feels, DmC's enemy line up is truly awful where a good third of the enemy roster features immunity to six of your eight available weapons at any given time. As both of the Angel/Demon stance exclusive weapons feature an extremely limited moveset that barely constitutes a single proper weapon (Demon) or do the damage of a gnat ****ing into the breeze, either you're going to feel severely limited, bored and starved to do anything else, or you're going to sit there wailing on the same guy forever wondering if there's any way you can speed things up.
These guys single-handedly stifle any enjoyment there is to glean from the gameplay especially on SoS or DMD difficulties where it starts to give DMC2 a run for its money in regards to sheer tedium as the saturation of these enemies increase significantly to where you have to deal with high tier ******** enemies or weapon immune mobs in the most unpleasant and frustrating enemy groups (And not in the good way) at least twice in every fight.
Take that and combine it the lack of a lock-on ( http://www.youtube.com/watch?v=fdyLahqEQIw enable annotations) and specific inputs that barely work two thirds of the time with zero way for the user to knowingly correct the issue, you have a game that doesn't deserve the benefit of the review scores it has been getting, let alone the DMC label.
tldr - Stick with Bayonetta or MGR:R instead or if you must, just play and stick to the demo as it has all the weapons you're really going to use and it doesn't have as many instances of the horrid design choices that plague the final product. Once I got to mission... 12 in SoS where I have a four minute escort mission where all I can do is demon pull targets (Literally - they strip the player of any other action for the entire sequence) I said **** this noise and went back to dumping dozens of hours into DMC4. DmC will never hold up as long as 3 or 4 or even 1 could.
Nope, the gameplay is actually worse than the cheesy and childish dialogue.
