Bloodstained: Ritual of the Night, widely regarded as a Castlevania successor and led by Koji Igarashi, has been a phenomenon on Kickstarter. It's become the most successful game project ever on the platform, and its success has brought plenty of stretch goals and a particularly neat tie-in with Shovel Knight.
The campaign has now ended, and it had an extraordinary final day that saw it close on $5,545,991, passing every single stretch goal. The latter goals include an Inti Creates-developed prequel minigame that'll even come to the 3DS - think Mighty Gunvolt - and even a roguelike dungeon mode, which will extend replayability a huge amount. Coming in 2017, the full game (and mini prequel) will arrive on the Wii U eShop.
It's been an outstanding crowdfunding effort, and now the hard work begins on developing the end product.
