Heh, to be fair, I actually hate DMC3... *puts up flame shield and runs to bunker* ._.
I like DMC 3 but everyone has an opinion and shouldn't be flamed for it. In terms of DMC 4 story that has little to do with this thread but I will try to connect it. Most game story line fall under a category now. You can usually compare the story of a game to a different game. So I believe that characters make the story more than the actual story.
I like Nero because he is a lone wolf, rebellious teen, that isn't afraid to show emotion. I am more interested in what happens to Nero than I am the story as a whole. If I was more interested in the pure story than I would probably be let down by most games.
