Editing Simulation (section)

====Early history (1940s and 1950s)====
The first simulation game may have been created as early as 1947 by Thomas T. Goldsmith Jr. and Estle Ray Mann. This was a straightforward game that simulated a missile being fired at a target. The curve of the missile and its speed could be adjusted using several knobs. In 1958, a computer game called ''[[Tennis for Two]]'' was created by Willy Higginbotham which simulated a tennis game between two players who could both play at the same time using hand controls and was displayed on an oscilloscope.<ref>[http://www.pong-story.com/intro.htm Welcome to PONG-Story] {{webarchive |url=https://web.archive.org/web/20100827183321/http://www.pong-story.com/intro.htm |date=27 August 2010 }}</ref> This was one of the first electronic video games to use a graphical display.
