Since the Apple II, Macintosh, IBM, Commodore, and Atari computers all had varying graphics capabilities and different processors, releasing a software title for each different brand of computer usually involved programming it again from scratch for each platform. Penguin Software/Polarware began focusing on cross-platform ideas that would allow them to release games simultaneously on different systems without the lengthy re-programming process. The compact images from "Graphics Magician" could be used across platforms, and an adventure game development and deployment language called "Comprehend" was created to be system independent and was used for several releases. Also using "Graphics Magician" across platforms and with a portable design, the first three titles in the "Adventures Around the World" geography game series were released. However a similar idea called "Where in the World is Carmen Sandiego" reached the market a few months sooner and doomed the Penguin Software series.
