Frotz (App Store), the nostalgic interactive fiction application has appeared in the iTunes App Store. This application plays games made in the Z-Machine format -- a game format created for text adventures by Infocom in the 80s.
Frotz text-based adventure games played by typing in commands into the keyboard. A version of Frotz was released on the jailbroken phones a few months ago - it's good to see it now on the iPhone OS 2.0 platform.
This version comes with a few different games and also connects to the Internet to allow you to download additional games.
