But did it really have much growth? DMC1 on the PS2 sold 2.2 mil, and DMC4, 7 years later, sells 2.7 mil. That's not much, especially considering the cost of next gen development in 2008. DMC4 was also front loaded. Now, like I said, I don't think DMC5 would have sold as great either. DmC's sales are more complicated than simply "pissed off the fanbase" I honestly think much of the blame can simply be put on the genre's current popularity.
From my own anecdotal experience, most of the people who I knew that picked up DMC4 thought it was a "good game, but not great". Of course, none of these guys replayed it or got into bloody palace or any of that. They're guys who play a game once, and that's essentially it. They knew DmC was coming, didn't care if the character changed, but didn't pick it up simply because they just don't keep up with genre anymore. It's a shame too, because I've known them for years and they used to love the genre back in elementary and high school (I remember when DMC2 came out, we were all so hyped up for it, lol). Just my own experience, but I think it can be applied generally to the changing gamer habits over the past 5 years.
