Out of the Park Baseball was born in 1998, when lead developer Markus Heinsohn had the vision to combine a highly realistic baseball simulation with career play. His goal was to create a game that allowed users to run a virtual baseball franchise. With realistic statistical output, the game was satisfying to hardcore baseball fans and casual gamers alike.

Title Bout Championship Boxing is the latest rendition of a professional boxing simulation that dates back to the highly successful and current cult classic board game, Title Bout: The Game of Professional Boxing, produced by Avalon Hill Game Company.

In 1976 Jim and Tom Trunzo began selling their board game boxing simulation, under the auspices of Jim Barnes' Statis-Pro Games, a humble effort simply called Professional Boxing debuted with fifty rated heavyweights. Enough interest was shown in the neophyte product to encourage the 1977 release of a mail order product entitled Truco Championship Boxing, which contained over 200 rated fighters from boxing's eight main divisions.

Markus Heinsohn is CEO and co-founder of Out of the Park Developments, and the lead designer and developer of Out of the Park Baseball and Inside the Park Baseball. In 1999 at the age of 21, Markus developed and released Out of the Park Baseball, a critically-acclaimed baseball simulation that has evolved into the most complete baseball management sim on the market. He studied computer science at the University of Hamburg, Germany, and lives in Heinbockel, a small village near Stade, Germany.
