There's a new Stardew Valley-like doing gangbusters on Kickstarter, and it originally looked so much like ConcernedApe's farming sim behemoth that the developers had to redraw the whole thing.
Super Zoo Story is explicitly inspired by Stardew Valley and Harvest Moon, but in a FAQ, the husband-and-wife development team revealed the art was originally so similar to Stardew Valley's art that it received "feedback" and had to go back to the drawing board.
