Thirst no.3 by Christopher pike! Question!?

This is random, but nonetheless, Christopher Pike (through Sita "Alisa") talks about a game that John plays called C.I.I. (I can not remember what it stands for, and I dont have my book on me since Im out of town.) does anyone know if its a real game? I was just wondering if it was because it sounds SSSOOO intresting! PLEASE answer any of this as soon as possible, curiousity is killing me(:
