Operation Akumajo...who successfully alienated the majority of the Castlevania fanbase as I recall
I think that Konami did just fine on their own alienating their fanbase, they really didn't need a lot of help.
This sort of thing is going on all over the place, though. I feel that Square Enix, Capcom, and quite a few others haven't really done a good job of listening, or recognizing what made their companies successful in the first place. Square Enix may be trying to save face with a supposed FF7 remake, for example, but the fact that the traditional JRPG battle system is being completely remade to something more "modern" seems to be directly analogous to Konami's abandonment of the 2D genre.
Maybe money has something to do with it. Maybe the financial reality truly IS that people won't buy the "old" stuff enough to make it viable for a company (I doubt this is the case being that I bought a PS TV just for the Dracula X Chronicles and FF IV Complete), but I also think poor marketing plays a hand for Konami. I mean, I loved Hard Corps: Uprising, but come on! Why were too dumb to include "Contra" in the title of the game? Sales might have been remarkably better had they done so and people were AWARE of it, enough that I think they could have concluded that the genre and style is NOT dead..
