Adventure Maker - https://www.adventuremaker.com:
Adventure Maker is particularly useful for creating first-person adventure games, such as Myst or Riven. After adding pictures for the backgrounds (BMP, JPG, GIF,WMF or EMF), the user can add hotspots, texts, animated gif's, sounds (WAV's, MIDI's or MP3's), videos (AVI's), timers, variables, items to be picked up and much more. The program can create single, fully-featured, compressed, stand-alone installation files, so that software can be easily distributed also over the Internet. Particularly user-friendly (drag and drop support, Windows Explorer style...), the program can be used by beginners as well as experts. Free online tutorials are also available for fast learning of basic and advanced functions.
