Wander

Wander is a text adventure written by Peter Langston in 1974. It is one of the earliest text adventure video games in existence, predating Colossal Cave Adventure. The game was originally coded in BASIC on a mainframe computer with multiple databases to create the worlds that formed the game. It was distributed in Langston's PSL Games collection for Unix. For a long time, the original files had been kept in an archived email by one of Langston's friends. The files now exist on GitHub.
