Zach Adams started the Mesa Vista build a city challenge by establishing a basketball-themed business called Zach's Hoops. After many days, the business became successful and allowed Zach to fund a public park and university. Zach then moved three friends into the neighborhood to unlock the military career. He pursued relationships with Diane Shin, Kerie Ng, and Marie Sims, eventually choosing Marie as his wife. By the end of week 1, Nikki Chan was pregnant with Zach's child, qualifying Mesa Vista for the military base and beginning the expansion of the new city.
