^ I remember liking Capture the Flag
in particular from the SFA line, mostly because I played the game as a kid
I even pitched a YA novel to Pocket way back when (Riker and other cadets vs. Orion pirates...I'd even written the entire story because I didn't read that part of the submissio guidelines which read "Don't do that shit."), and received a very nice rejection letter from the editor at the time, letting me know everything I was thinking and doing wrong with respect to my story and writing sample.
Bottom line? Writing correctly for the kids/teens market ain't easy.
