Nostalgic for a simpler time? Then take advantage of those crisp high-resolution fonts to relive the glory days of the Great Underground Empire, or play any of hundreds of great works from the Interactive Fiction archive. Frotz lets you play free works of Interactive Fiction (a.k.a. text adventure games) on your iPhone, iPod Touch, or iPad. Frotz plays titles written in the Z-Machine format. This format was invented by Infocom and was used to produce classic text adventures from the 80s such as the Zork Trilogy, Hitchhiker’s Guide to the Galaxy, and Trinity. In the past decade, text adventures have experienced a renaissance due to the efforts of a diverse Internet community of talented interactive fiction writers and fans. Many of these games are written using the same engine that powered Infocom’s titles, thanks to the Inform compiler and authoring system created by Graham Nelson.
