The first Kickstarter project I ever pledged to was the
Quantum RPG by Joshua Frost. At first there were regular updates and progress seemed good. Then the updates got less frequent, and the last update was that the project was dead.
Launched: 10/31/11
Estimated Delivery: 4/12
Last Update: 5/6/14
Then there was the
N.R.G. Core Rulebook by Game Smiths LLC. In their last update, they sent out their Sinbad setting to everyone, but then went silent (and deleted their creator account).
First Update: 7/21/13
Estimated Delivery: 4/14
Last Update: 2/19/15
There was also
Dragonheim, by Varon Cook. They did fairly regular updates with previews and then just suddenly fell off the face of the earth.
First Update: 8/15/13
Estimated Delivery: 12/13

Shinobigami is one where I'm still waiting for my limited edition book. Which was kind of surprising, because I had backed both their Tenra Bansho Zero and Ryutama KS prior to that, and while I think those were late, they did deliver and the quality was excellent (in my opinion). I think, as has been mentioned, that there might be some undelivered stretch goals for those projects, but those don't concern me as much.
Hunter's Mark was another one. They delivered a PDF, but nothing more.
Reach of Titan, by Jim McClure, is another one that hasn't delivered, and has been radio silent for years. This one's arguably the biggest bummer, as I was excited for the concept. I'd be overjoyed if they suddenly popped out of hiding and delivered the game, but it doesn't seem terribly likely at this point.
Launch: 1/29/19
Estimated Delivery: 1/20

Children of the Beast, by Nicholas Kitts, is very late but the oldest one that I think still has a decent chance of being delivered. They've sent out draft versions of the game, and appear to still be working on it as of the last update. Fingers crossed.
Launched: 6/11/19
Estimated Delivery: 4/20

That said, I back a LOT of Kickstarters and most of them are TTRPGs. These represent only something like 2-3% of the TTRPGs and supplements I've pledged, the majority of which have delivered as promised (albeit, frequently late). It's always disappointing when something like this happens, but cest la vie...
