I would understand if there was ANY reason for not giving him a face. But there is none. I really can't see one. And I would buy this sense of mistery stuff, if it was something like Master Chief's face. Like people were trolled, getting cut of the shot just before the moment the face was shown, but not here. Here the face is just non existant, there is nothing to it. Yeah, maybe my logic is flawed here, but it's my opinion after all.
It's leaving things to mystery for a sequel, or something. Thing to reveal later. There's any number of reasons to leave the features of a character hidden, and it's usually to create mystery and for something that can be drawn upon later. Laziness just doesn't mix with the equation.
It also
could really have been about paying homage to the mystery of the classic Sparda. I still believe we don't actually know what his real face looks like, because every model used for him as a skin is just Dante's face...so either it's really just a costume Dante is wearing, or his kids looked like carbon copies of him >.<
C. Sparda did some fighting as well. Wasn't he the one to fight the whole army of demons amongst the humans? And his deeds actually draw the demons back, giving Eva the time to raise and train his children to be the demon slayers they became.
Classic Eva had no hand in Dante and Vergil's fighting proficiency, she was just a swell gal that Sparda loved, and a neat mom to the kids. She gave them the Amulets, but even then they weren't hers...she got them from Sparda, who got the Perfect Amulet from the humans...who got it from Mundus >.<
And Sparda fought alongside the humans against the demons. That's good, I'd just actually like to know
more than that. What makes him such a legend over all the other great people he served with? Y'know?
I feel much like you - I think that the developers did a lazy job in expanding upon
why classic Sparda is supposed to be seen as "legendary," because all they did was keep telling me he was. I'm just not wholly convinced :/
Part of the reason why so many want a DMC where you play as Sparda, and experience things through his eyes to really learn the "why" of it all.
