Fair use for Commander Keen series, Vorticon and id Software
I, Sega381 04:11, 8 October 2006 (UTC), feel that this image is appropriate to be used in this article under fair use because:
 * id Software has not released any such images to the public domain
 * It is a low resolution screenshot of the game
 * It does not limit the game's copyright owner (id Software) to sell the game in any way
 * The image is being used in an informative way and should not detract from the game
 * The image is used to illustrate important characteristics of the game mentioned in the article, which conveys to the reader an idea of what they look like
 * The image's only purpose is to aid in the description of the fictional world of Commander Keen, and for no other purpose
