DmC's art direction and aesthetics kicks all kind of ass.Not just the visual look of the place either, but also the way they incorporate the stuff. With the upside down prison comprised from the reflection underwater, to floating news icons and a demonic rave. If there's one thing people can agree on, is that the game is beautiful, creative, and like I said, kicks all kinds of ass in this regard.
Limbo feels like its living, breathing evil entity hell bent on Dante's demise. Tell me another game that does the kind of stuff Limbo does in recent memory? I can't think of anything off the top of my head. This stuff is done in real time too, they don't need to cut for some cutscene or put you on some Uncarted like rail car when you're traversing it. Plus, there's tons of little details scattered about which really helps you getting immersed in this world.
As for the gameplay, it's Devil May Cry. It do what the Devil May Cry do. All part of the same series. DmC is NOT a separate franchise or anything. It did however bring some mechanics to a more natural evolution that was appreciated. The originals didn't do everything right with some of its arbitrary combat mechanic choices.
So yea, it's not something that should be forgotten even if the next game is just a traditional Devil May Cry game. That would just be going a little backwards.
