Koji Igarashi, designer of
Castlevana: Symphony of the Night, has a Kickstarter for a spiritual successor. The Kickstarter promises Steam for Linux as a launch platform.

"Devs Play" Special - Castlevania: Symphony of the Night
Personally, I laughed at the RING OF IGA Kickstarter reward. IGA is a chain of supermarkets here.
