Raph Koster’s career spans the evolution of the modern MMO. Creative lead on MUDs, Ultima Online, Star Wars Galaxies, and EverQuest 2, the systems and mechanics his teams developed live on in every active MMO today and many games besides. “People made fun of me for having dancing in Galaxies,” Koster tells me. “Fortnite ought to give me royalties.” But the promise of his new game, Stars Reach is a scale bigger than everything he’s made before.
