I consider Data Boxing to be the best boxing sim and possibly the best sports replay game ever. In fact, Data Boxing is the best...I repeat...the best...sports game that I have played. Data Boxing began as a research project in 1967 by Dr. Julian Compton, Humanities Professor and Boxing Authority [1940-2010]. It is based on over 40 years of research. Each boxer is represented a card which shows his abilities on offense and defense for more categories than one would imagine. (The heavyweights champs are evaluated on up to 155 variables).
I have been playing Data Boxing for 30-odd years (mostly with the computer version the past six years). Besides being tops in entertainment, Data Boxing is educational. There is a lot of history to be discovered in the world of Data Boxing. Data Boxing is based on decades of study and research by Dr. Compton and the sport of boxing and boxing fans are benefited by this historical boxing simulation.
Dr. Compton was one of the best, though less publicized boxing historians and his gaming concept makes it possible for boxing enthusiasts to use an objective, mathematical approach to the evaluation of boxers using the premier simulation of boxing, Data Boxing. To quote from a Tallahassee Democrat new article from 2006, "I think if you have complete data and a fair analysis, then you can make a consistent mathematical analysis" (said Compton).
The scientific principles upon which Data Boxing is based make it an accurate boxing simulation. Data Boxing was popular with boxing writers and featured in the December 1977 edition of Ring Magazine, the May 1977 and December 1977 editions of Boxing Illustrated magazine, The People's Almanac , Computer Sports Matchups , All Sports Digest, Tabletop Sports, and in the December 13th, 2006 issue of the Tallahassee Democrat. To quote from Julian Compton's [aka drdatabox] user page at BoxRec: "The game was popular with boxing writers, due to it's obvious awareness of information below the headlines of boxing history, and it's mathematical structure, which allowed for the matchup of boxing greats from different time periods."
As noted above, I have been playing Data Boxing for 30-odd years (started playing the table game in 1981). In the 1980 edition, Dr. Compton wrote: 'Data Boxing is one of the most detailed and accurrate sports games you can play. Whether you are six or ninety-six, it is a game you can play for a lifetime.' Indeed, this game continues to give me enjoyment and it has been educational as well. I see this wonderful game as a lifelong guide to the study of boxing history and to draw probable conclusions and I'm having a good time in the process. What would I have done without Data Boxing!
