The folks at Double Fine, the Tim Schafer-led developer, make comedy look incredibly easy, particularly when Schafer is writing the script. Schafer has an ear for clever dialogue, but his real strength is characterization. He’s great at creating believable people stuck in unbelievable situations, and his heroes dive in with gusto. Psychonauts is arguably his most successfully comedic game thanks in large part to the basic gameplay of the platformer. Because each stage the hero, Raz, explores is inside the mind of Psychonauts many wacky characters, it makes each level a minefield of great jokes.
Take the conspiracy-obsessed Milkman. He has a twisted view of the world that makes for great conversations, but when you enter his thoughts, the looping, upside-down world is full of the mysterious men that haunt his dreams. In his level (like all the others), you come to understand the already-funny characters on a new level, which further enhances the comedy. Psychonauts is the best example of the unique brand of jest that only Schafer and his team can pull off, and given how difficult crafting just one good joke can be, we’re not surprised his games are continuously delayed.
