Unfair Games needs a commercial success after the fate of Both Sides and gets it in the form of Counterpart High. Counterpart High (CPH) is the brainchild of Simon Freeman and Antonio (Ant) Ruiz, two young men who joined the company recently. Initially titled Love Doppelgangers, CPH takes place in a high school, where each character can summon alternate versions (lovers, doppelgangers) of themselves through wormholes. CPH is released in February 2001 and becomes the most-sold PC game in America within four months of its release.

Sadie is happy for Simon and Ant’s success—who are a couple—but sometimes feels left behind in her own company, especially since she hasn’t found an idea for a new game of her own. However, though she doesn’t acknowledge it, she has a huge part in CPH’s success. Sadie mentored Simon and Ant, and CPH was built using her engine. Sadie wishes for a relationship like Simon and Ant’s, but she thinks if she and Sam were a couple, gender bias would ensure people slotted her into the “helper” role of the professional collaboration. Meanwhile, she falls into a comfortable friendship over the phone with Dov. They often discuss their work, and Dov is generous with his praise for Sadie’s career.
