Thompson has also criticized a Christian video game based on the "Left Behind" series. In "", players participate in "battles raging in the streets of New York," according to the game's fact sheet. They engage in "physical and spiritual warfare: using the power of prayer to strengthen your troops in combat and wield modern military weaponry throughout the game world." Thompson claims that the makers of the game are sacrificing their values. He said, "Because of the Christian context, somehow it's OK? It's not OK. The context is irrelevant. It's a mass-killing game." "Left Behind" author Tim LaHaye disagrees, saying "Rather than forbid young people from viewing their favorite pastime, I prefer to give them something that's positive." The dispute over the game has caused Thompson to sever ties with Tyndale House, which publishes both the "Left Behind" books and Thompson's book, "Out of Harm's Way". Thompson has not seen the game, which he says has "personally broken my heart," but claims, "I don't have to meet Abraham Lincoln to know that he was the 16th president of the United States."
