Finally got around to playing it. It's a good game, but just like DMC4 there's some stuff holding it back. Namely the addition of V, story structure, and level design.
Although I've read that people enjoy playing as V, and I totally understand from a plot standpoint why he is so central to the story, I really wish they had excluded him from being a playable character in the game (and instead have his story only told through cutscenes). In doing so, I don't think the story would have really been affected to a great extent.
Story structure itself is kind of all over the place. I get that jumping back and forth is a popular way of telling some stories, but I never found it particularly effective when the story can just be told "as it happens" (i.e. in chronological order). I guess you could argue the series as a whole has done this in the past, where the story goes DMC 3 > 1 > 2 > 4 > 5, but that's really only one game out of 5 games being out of place, and not jumping back and forth.
The consensus seems to be level design is the worst thing about thr game, and now I know why people were being so critical before I got a chance to play it. Should have been a match made in heaven, with the RE Engine being so capable and DMC's iconic gothic theme. However, Red Grave City is so devoid of character, is ugly, and feels like a big corridor. I'm not expecting an open world (hell no as that's awful, especially for a DMC game), but I felt like I was super constrained and wished there would have been a lot more thought and care put into the level design.
However, aside from that the character design for Dante, Lady, and Nico were great. I'm not going to go into too much detail about Nero and Vergil, though they both look "off" for some reason (likely the hair), and of course Trish looks awful as everybody said.
Obviously the shining star is the combat, and it delivers in spades. I'm not the best DMC player when it comes to movesets, so it was nice having Nero as a playable character as I think he is the most accessible. The number of different Devil Breakers add some good variety, and the extendable arm that either drags you to enemies or pulls them to you is a nice touch. Dante of course has his usual set of unique weapons (and surprisingly despite going with a more realistic art style, his usual whacky animations where he showboats whenever he gets a new weapon).
Overall I honestly think this game is tied with DMC 4. It does some things better (no back tracking), but it does some things worse (level design and inclusion of V as a playable character), but was a great addition to the series and if this is the last game was a good enough send off.
