Whether it came from a pizza box or an unnamed Wells Fargo banker, Herman Cain’s 9-9-9 economic plan is now being compared to another unlikely source: the SimCity video game.

Long before the GOP presidential candidate’s plan began dominating the political discourse, a shockingly similar 9-9-9 plan was ruling the virtual world of SimCity. In the video game, residents of SimCity 4 pay default taxes that include a 9 percent commercial tax, a 9 percent industrial tax and a 9 percent residential tax, Huffington Post Politics pointed out.

Cain’s plan implements a 9 percent sales tax, 9 percent personal income tax and 9 percent corporate income tax.

When asked about the similarities, Cain’s campaign spokesman JD Gordon said, “Well, we all like 9-9-9,” the Huffington Post reports.

Kip Katsarelis, a senior producer for SimCity’s production company, Maxis,  said the company likes that their ideas for video games are being attempted in the real world.

“We encourage politicians to continue to look to innovative games like SimCity for inspiration for social and economic change,”  Katsarelis said, according to the Huffington Post. “While we at Maxis and Electronic Arts do not endorse any political candidates or their platforms, it’s interesting to see GOP candidate Herman Cain propose a simplified tax system like one we designed for the video game SimCity 4.”

He said game developers chose the simple tax code so gamers could focus more on “ building their cities and have fun thwarting giant lizard attacks, rather than be buried by overly complex financial systems.”
