I feel like Mighty No. 9 really taught people the perils of Kickstarter. I didn't pay into that one but I watched the drama unfold and sat back thinking that as bad as this thing went, no other developer is going to make this same mistake. Yet it looks like we may be seeing it again with Bloodstained. Every time an update is released for that game, it's basically "This is taking longer than we expected and we are only 20% done with the game" followed by additional delays.
This is what's wrong with most of the KS projects, as they take the creative types from these companies, and then give them funds, that they have no idea how to use properly. When your working for a publishing house, you have people who's job it is to watch the money, know where it's going, and have 100% accountability. When deadlines aren't met, someone has to answer for it, at some place in the chain.
Now with KS, you get guys who should probably never have that responsibility in the positions of power, and it rarely if ever works. Creative types rarely if ever understand finances, and the bean counters rarely if ever under stand the creative process, but together they make things happen. Apart from one another, it's a huge cluster

95% of the time, sadly.
Every KS I've backed from a gaming standpoint, which has only been a few, have always not delivered 100%. And as I stated above with Shantae, I'm still waiting on other items. When I've backed gaming book items, they have delivered every time, with everything promised, with little to no delays. So KS is a great tool, when used properly, but as I stated, creative people rarely if ever understand things on the finance side of things, and the KS game campaigns are 100% proof of that.
