It sounds like your issue is that you didn't like IGA's Castlevania games to begin with (or at least the later ones) which is your right. I'm not arguing that.
I liked IGA's Castlevania games just fine at first...until it became very clear that they were all the
same game (namely Symphony of the Night, a game I find rather overrated anyway) with minor differences. But Aria of Sorrow & Dawn of Sorrow are classics. Hell, I even liked Portrait of Ruin for the way it tried to break out of the mold & try something new. Order of Ecclesia was offensive, though, for what it did to what was allegedly a "strong female character".
I have a pretty good idea of what to expect. It kind of seems like you do too which is what makes this unappealing. What makes this stand out? Well, I can't speak for anyone else, but what I really want is Castlevania. I can't get that anymore so this is probably as close as I'm going to get.
My issue with Igarashi is that he's always struck me as an incredibly
lazy developer. All his Castlevania games are permutations on the same damn formula, and most of
those use stock sprites from far older Castlevania games. So yeah, when it comes time to go to the internet and beg people for money because no one wants to give you a job (because no one thinks you're reliable or noteworthy), I expect to see some goddamn effort. Instead, all his Kickstarter is is "hey, look at me! I was relevant once! Give me money because of that, and because **** KONAMI!!" He even has the sheer ego to call the game an "Igavania", as if he and he alone were creative enough to add RPG elements to the Metroid formula.
So yeah, I don't like the guy, I don't think he belongs on Kickstarter, and I don't think he's justified his project's existence. I'm inclined to be sympathetic towards his project because I'm
also of a "**** KONAMI" mindset due to how they gutted Silent Hills, but he has to
earn that money and so far he's skated along by doing very little. It's a small amount of flash and name recognition trying to divert from the fact that
there is no substance. He has
nothing to show after all these years of working on
nothing since leaving Konami. If you ran a video game publisher, and he walked into your conference room with
that as his pitch presentation, would
YOU give him money? I sure wouldn't. Yooka-Laylee's? I'd consider it.
And, incidentally, Bloodborne is a far better Castlevania game than most of Igarashi's games. There, I said it.
