You might know Psychonauts as the "psychic adventure from the mind of Tim Schafer", but it was also the game that shaped Double Fine Productions as a studio. The part-platforming, part-adventure game started out as an obscure concept in the 90s, became a huge critical success on launch, then, slowly, evolved into the beloved cult classic it is today, with a sequel set for 2019. In the latest episode of IGN's Expert Mode, we sat down with Tim Schafer himself to talk all about the challenge of originality in modern game development, the importance of wish fulfillment for players, and unique strategies for coming up with consistent characters.
