I know the discussion topic asks about making Dante the main character instead of Nero, but opening that door of making adjustments to DMC4 just made me think a little beyond the topic, to what I feel would overall make DMC4 a way better game, both story and gameplay-wise. My Top Ten Devil May Cry 4 fixes in no particular order:
1. Dante has to be more consistent in his style and personality based off of DMC1. In DMC4, he appears to have no idea of what's going on. He has no previous knowledge of Nero. No knowledge of Fortuna. No knowledge of The Order of the Sword. No knowledge of what Yamato is doing in Fortuna. He appears aloof and air-headedly pleased at the end of the game when none of these subjects are resolved or spoken about at length. He apparently cannot take anything seriously: Sanctus murders Credo in front of him and Trish, stabs Nero, flies off, and Dante's major contribution to the scene is making fun of Nero while all of this happens. And to top it all off, he's loud, immature, and prances about the game as major characters die and major plot points occur without any sense of urgency or relevence. Whyyyy? Fix it.
2. If you're going to split the game down the middle, don't make Dante's half a re-tread. Seriously.
3. Nero's Devil Bringer finishing moves were super cool and added a new dynamic to the boss battles. Dante needed something creative of his own to match Nero's finishing moves, or else you end up just waiting for the boss's health to time out while mashing triangle whenever you play as Dante.
4. ERASE THE DICE GAME. NO ONE LIKED IT. DUMB. AND FRUSTRATING.
5. Trish and Lady were laughably underused. Trish as "Gloria" never gave the satifaction of ACTUALLY seeing Trish. And Lady's non-presence left a hole in my fan heart. Trish and Dante need more buddy face-time for big action and character driven sequences. And if Lady's gunna be in the game for a short time, at least have her come back for the game's final act, flying Dante's bi-plane, coming in to save the day or something. CAPCOM had a huge opportunity to bring all these character's together in an interesting and satisfying way, and wasted it.
6. Alot of hate on Kyrie is understandable. I always liked her, but there needs to be something more to Kyrie's character. I love the idea that she's a human and not trained with weapons or badassery. Not every woman in the series needs to be a Trish or Lady. Kyrie's weapon is love, and it would've brought a fresher perspective if utilized more.
7. Fortuna needs to be explained. There's alot of subtext that says Sparda ruled there at one point. Where better a place for Sparda to "quietly reign the human world until his death," then on a secluded island where he could oversee that the Humans were kept safe? Wouldn't it make sense that Fortuna would've been Sparda's home on Earth? Also, with the whole city built around him, where better a place to father and train his sons Dante and Vergil? Following Sparda's death, it only makes sense that those who desire power would deify Sparda's image and corrupt Sparda's word by martyrizing him into a religion. Using Sparda's image as power to enslave Fortuna would be a natural progression in Fortuna's story and a timely and relevent critique of modern religion in general. Thus, Dante and Nero bringing the true power of Sparda back to Fortuna (Not through enslavement to religious doctrine, but though love) would have been a much more meaningful pursuit. It makes no sense for a place that's as potentially important like Fortuna to exist, and for Dante to know nothing of it.
8. Mentioned above. Vergil is Nero's father. Why? When? How? With who? How does the Order have Yamato? Big plot points that are left up in the air. I do like the idea of Nero being the main character, but if either Dante or Nero is going to helm this one, both of their characters need some serious attention. Nero's blank slate backstory is infuriating.
9. Let's face it, Agnus was a pathetic Arkham re-tread with half the brains, and even less of the imagination. This guy needed to be left at the drawing board.
10. Something that's never been addressed in the games is the political climate of the Underworld. Mundus was their Emperor. Following the toppling of Mundus's regime, what's happening in the Underworld afterwards? It's clear, through the game's use of the Hell-Gates, that there are very powerful demons in the Underworld such as "Berial, Conqueror of the Fire Hell." Who's going to try and take Mundus's throne? Shouldn't Dante be more concerned with someone like that? Perhaps maybe even... Argosax? By trying to take over the Human World (which Mundus was never able to do) by using Sanctus as his vessel through the "Asension Ceremony," Argosax would be the prime villain to introduce into the game for Dante to take on to protect the Human World. Bringing Argosax into the picture would have given a far better reason for Dante and Trish to come to Fortuna, than Lady simply putting them on a job. Not to mention the "wings" around Sanctus Diabolica look very similar to Argosax's wings in his "Despair Embodied" form. Dante and Nero would stop him in Fortuna, but using the same method of using a weak human like Sanctus as a vessel, Argosax would resurface again through Arius, and finally be defeated in DMC2. Thus both games which by themselves have no purpose to the overall series plot, could be connected through use of Argosax. This would also make an irritating re-tread of a plotline (Random old dude wants the power of Sparda ..) fresher and more interesting.
