I didn't go in completely cold as I watched a bit of YouTube video but you never really know until you actually play the game itself. I was even very critical of the game prior to it's release, especially when I saw the part (which is also in the demo) of Dante fighting the giant larva creature where they exchange quality dialogue.... "fuck you! No, fuck you!" etc. I was actually pleasantly surprised how well the game felt when I tried it and at least to my memory, seemed pretty spot on with the feel of DMC, or at least the last DMC game I played which would be DMC4. My only issue right now would be the somewhat 'edgy' characters and what seems to be a repetitious city environment. I also noticed there seems to be a lot of platforming in this game, but that's not necessarily a bad thing. Some of these types of games actually lack platforming. But, I'm pretty sure I'll find this game at least somewhat entertaining. I've finished DMC1 and DMC4 both twice and I still find this series to be top tier when it comes to the genre - even better than GoW and NG, which I both love as well.
Edit: Also played the demo for MGS:R last night and that has a nice, similar feel to NG. But that voice acting.... Ugh.
