I mean nero has a ton of character development potenial i mean his back story and origins laone combined with dante being elsewhere in hell and the demons rising to try and take over and nero being the new hunter could make an epic game. give him the use of a new improved darkslayer style (similar to the dmc3 vergil version) but also similar to dantes trickster give him the use of both red queen and yamato as primary weapons with the ability to switch between both and give him a new gun maybe some kind of shotgun of thtrowing knife's or some kind of other projectile maybe giving the devil bringer some kind of projectile move similar to summoned swords? and you have your self a game good thought out enemies great one liners great enviroment and gameplay with new enemies and the option to play as dante or vergil as well and youve got yourself a game
