Psychonauts (2005)

Psychonauts' long route to a fan-supported sequel makes sense when a mind becomes a place with its own rules. The Milkman Conspiracy turns a neat neighbourhood into a maze of paranoia, with disguises and suspicious behaviour becoming part of the joke. Raz's psychic abilities make those ideas explorable. The original's comic performances and imaginative levels are the reasons to start here. Allow for older camera behaviour and sharp difficulty changes near the end; its following does not make those rough edges disappear.
