As a 69-year-old who grew up in Birmingham, Ala., Lawrence Walker remembers a time when people were more likely to judge by the color of someone’s skin than the content of their character.

But the retail clothing entrepreneur and Inglewood resident is worried that young people today fail to appreciate the events and historical figures that have helped America become a world power.

To help them learn — and to jog the memories of those who have forgotten — Walker has teamed up with his son, Taylor Walker, to create a trivia board game that aims to educate, not just entertain.

The game, called Earth Encounters, quizzes players on subjects like history, religion, politics and art and prompts debate on social issues.

“I was amazed about how little people know about our country and the news that impacts us on a daily basis,” Lawrence said. “I wanted to do a game that, after spending two hours in the evening playing with friends, you feel like you’d accomplished something.”

The premise for Earth Encounters is that an alien life form that feeds on human knowledge has landed on Earth. To defeat the alien, players must use their intellect to answer questions and advance across the board.

What are symptoms of a heart attack in men versus women? Who changed the world more: Google or Facebook? If you were Abraham Lincoln, how would you defend the Emancipation Proclamation?

There may not be a definitive answer to a debate or role-playing scenario, so players must use their powers of argumentation to win debates and are judged by the other players.

Taylor, an MBA student at Loyola Marymount University in Westchester, has launched a Kickstarter campaign to help the father-son team raise $15,000 to mass produce their working prototype. By Monday, the Walkers had surpassed the goal at $16,060. The fundraising campaign ends April 16.

The hobby game market grew to $700 million in 2013, according to market researcher firm ICv2. However, collectible games made up the majority of the industry, at $450 million. Board games accounted for about $75 million.

Earth Encounters has helped Taylor apply what he’s learning in business school to a real life situation. Starting a business requires an understanding of business law, accounting, budget projections and marketing, he said.

“It’s all about putting yourself out there and getting people on board.”
