Is there a Mantracker video game

No, but you can play a MANTRACKER simulation in the video game RED DEAD REDEMPTION. We play this on Xbox Live all the time. Their is numerous types of terrain. Mountains, Great Plains, Forrests, Canyons, Deserts, and much more. There are ways to track people in the game too. The player being the tracker should familiarize them self with them. You can set way points on the map so finish lines are marked. And there is wilderness too. wolves, grizzlies, cougers etc etc. Check out Red Dead Redemption on youtube to see the game.
