When I say serious I mean it's not an anime cliched game where the main hero is afraid to cuss, is too honest, and is a sterotypical hero. I think this Dante is more of a rebel and that's more relatible. An example is like this of the difference between a hero and a rebel.
Old Dante is a hero in my book.
New Dante seems to rebelious and pirate-like to be a hero.
The dog-eat-dog way of life that new Dante lives by is kind of like the life of reality. Thus why I say, "serious."
Just by projecting Dante's life like a junkie doesn't make it "Realistic" or "Serious" On any grounds !! and neither does Cussing after every alternate line makes it any realistic that just makes him Look like a Random junkie you can find anywhere in the world that nobody cares about
If you want to play a "Realistic" game which Actually portrays Human evil's Play Silent hill 2 its dark and it has very much Acceptable story unlike this ...
He ain't OLD ! He's just 30 Seriously his hair's white due to Demonic DNA and neither was DMC1 a cliche Anime Game ! Its the only Game which actually Has Blood -_-" even this "Serious" Game doesn't have Blood !
Really if Hero is stereotypical for you just some games with Anti-Hero's or Pokemon don't try to change Game characters just because you're bored of "Heroes"
