page jokingly insulting her skill at the game, Case publicly demanded a rematch with him. While Case initially struggled in the best-of-three rematch, she rallied back to win the first round 25–19, and went on to ultimately defeat Romero. As punishment, Romero agreed to set up a web page praising Case. Case was twenty years old at the time she won the rematch in 1997, and beating one of the co-creators of Quake at his own game brought her a lot of publicity. She gained a sponsor in computer mouse manufacturer SpaceTec IMC that year, and her victory against Romero received coverage in Rolling Stone. Angel Munoz, the founder of Cyberathlete Professional League (CPL), convinced Case to join his league in July 1997, becoming its first signed professional gamer. She eventually became one of the league's original founders. Case competed in the first all-female Quake tournament that year, coming in second behind Kornelia Takacs. Case moved to Texas in the middle of 1997. Describing her move, she said that while she had a passion for political science, she "was not excited about the day-to-day aspects of politics or practicing law." Transition to game design While playing professionally, Case began looking at game design as a potential career, stating, "I love games, and I love competition -- but having no choice but to play the same game day-in and day-out with all sorts of pressure attached just didn't suit my nature." According to Case, she did freelance game design work from her Dallas home for two years after university, using free design tools that she downloaded. One of the first game levels she designed was for SiN: Wages of Sin (1999). Setting up a small studio called Primitive Earthling Games, she and some friends created a Quake II add-on called Vengeance and submitted it to WizardWorks. However, it never became available for purchase due to publishing delays. Between 1998 and 2000, Case authored three strategy guide books for Prima Games: Jazz Jackrabbit 2 (1998), Buck Bumble (1998), and Daikatana (2000). She also contributed to their Quake II strategy guide. Case was hired at Ion Storm in the summer of 1997 as a video game tester. In November 1998, Romero offered her a job in level design, which she accepted. Case helped design levels for Daikatana (2000) and Anachronox (2001). It was during this time period that Case began to date Romero.
