2015 in Video Games by WangA

Question 8

What do these games all have in common? I'm looking for something fairly specific (e.g. the answer is not something like "they are all single player games"). Broken Age, Divinity: Original Sin (and Divinity: Original Sin 2), Hyper Light Drifter, Pillars of Eternity, Shenmue III, Star Citizen

They were all crowd-funded (on Kickstarter)
