Nicki Rapp? (Sometimes credited as Nikki Rapp)
She sounds strikingly similar, she’s played roles like random sims voices, Lilly in The Walking Dead game, Lili in Psychonauts and Dead-Eye Courtney in Broken Age.
For example, Dead-Eye Courtney in Broken Age, she’s the one in the blue robes. (spoilers for act 2 if you ever plan on playing Broken Age)
