So far back Project eternity,Wasteland 2,Grim Dawn,Arakion,Legends of Einsfald, Sui Generis and I am sure there are some more I can't remember atm.
From non gaming I backed Fallout nuka break season 2(They reached stretch goal where they bring Chris Avellone and Tim cain as co-writers and actors btw)and Space command.I am one of people that always complains about EA,Ubi and rest of crew so supporting kickstarter seems quite logical to me.
