This article is completely wrong. Chucklefish is Tiyuri's development team/company (who are indeed working on Starbound currently). The actual developer of Stardew Valley is ConcernedApe. Tiy's twitter comment was referring to the fact that he had come to an agreement with ConcernedApe to publish Stardew Valley. At least a minute of basic research would have revealed this. Perhaps fix the article so that the developer gets the credit that he deserves, unless this was actually an attempt to grab views by invoking the name of Terraria.
