Adventure is a series of fourteen text adventure and graphic adventure games primarily written by Scott Adams and published by Adventure International. Some of the games were first published by the TRS-80 Software Exchange in 1978-79 before Adventure International was formed.
The games were initially released as purely text adventures. The twelve originals were re-released with graphics as Scott Adams Graphic Adventures (SAGA) beginning in 1982, and the final two games debuted with graphical versions.
