I mean, people like to claim this when narrative fits it but it seems lots of people are enjoying Bloodstained so for the most part it did exactly what it was supposed to do. PC/PS4 versions are mostly fine with some technical issues and flaws only the Switch version is worthy of being laughed at with the "LUL KICKSTARTER GAME". It's a far cry from MN9.
But beyond this, old and played out stereotype is old and played out and not true. Plenty of successful projects have come off kickstarter. Total failures like MN9 are rare. FTL, Banner Saga, Shovel Knight, Divinity Original Sin, Darkest Dungeon etc...
I guess the problem comes with a game like Bloodstained or Shenmue raises millions and people expect them to be AAA games when that takes tens of millions so not even fucking close. Bloodstained was made for hardcore SoTN fans and for the most part they like it. Shenmue 3 was made for hardcore Shenmue fans and spoiler alert: they will like it and the rest of the gaming world will think it's trash because they don't understand what the fan base actually wanted lol. MN9 will be the lone exception where even megaman fans think it's trash.
