I don't know- they all had fuckery to them:
Mighty No 9- took forever, debacle over rewards not being fulfilled. Shoddy game.
Yooka Laylee- to be fair- the kickstarter campaign was fine, and the game was timely. Just a very middling end product.
Friday the 13th- the game- again, here the campaign itself was fine, game release was timely, and I enjoyed it for what it was, while I could- but alas the game got all future support yanked like a year later due to the problems in litigation over the Ft13 license, so it all feels like a waste, and if the license was in question, the project quite frankly shouldn't have happened in the first place.
Bloodstained- took forever to release, and wound up with a shoddy Switch port I truly thought would have more parity with other versions, instead of being a shitshow compared to other versions. Especially heinous since the sold more on Switch than anywhere else.
Shenmue 3- long campaign, game wasn't great, even to early 2000's Shemnue standards, after all this time, that's really the best they could do? Oh- and the whole Epic games debacle made me feel dirty supporting them.
Wonderful 101- kickstarter delivered the game, AFTER launch. fail. Don't. Do. This. Stop screwing backers.
So after all this (which all came about early in the ps4 gen), the only thing I've pledged for in years is Eiyuden Chronicle: Hundred Heroes - I have high hopes- they seem to have learned the lessons from what came before- but I'm not holding my breath- that said, as much as I wanted to support the shit out of this project, I only chipped in for a digital copy this time. Didn't opt for physical (and possible late shipping or people getting the game before me at a cheaper price, and a better looking physical package), and certainly not for any add-on swag, which almost always arrives well past the point anyone even cares about the game anymore. I'll just take a digital code, which should be easy to forward over whenever it launches. (and they physically promised in this campaign that the backers would get this first.- so if they break that, they got problems)
