I don't understand how some people's minds work, I really don't. Like when I say I think DMC1 Dante would be a popular skin in DMC4 SE, but then somebody replies saying 'do you really think Capcom reads forums?'
Why would Capcom need to read forums to know that DMC1 Dante is a popular character? It stands to reason. They are Capcom, they know all about DMC1 Dante and his popularity.
First off, Dante was a large part of the reason why DMC1 became so popular and gave rise to the DMC series. Even today, people still often find DMC1 Dante to be the best incarnation of Dante. You don't even need to read forums to see that. For the anime, they went with his DMC1 incarnation too, and many people have been hoping DMC will be returned to Kamiya (Platinum Games).
Second, DMC1 Dante was a popular skin in DMC3 too... why would it be any different for DMC4 SE? Besides, DMC1 Dante would go well with corrupt Vergil.
Third, people like it when you make references to past games, or include nostalgic extras. DMC1 Dante fits that bill too. I also think it would be a nice nod to fans of the classic games, and those who want DMC5. It could serve to hype things up even more.
Fourth, anything is better than a simple color swap. Do you really think a DmC color swap of all things, would be more popular to fans of the classic series than a DMC1 Dante skin? I realize making a DMC1 skin is harder than just taking an existing DMC4 model and altering it, but geez... if there's so few costumes in the first place, why not make them really nice to make up for that?
And these weren't even all the reasons why it's odd to think DMC1 Dante wouldn't be liked, I think.
