I was being sarcastic, wise guy.
And I can make an argument that some of the games you listed
do fit this plot:
Neverwinter Nights? Morag is trying to gather the Words of Power so she can take over the world and re-make it. It's up to a group of ragtag adventurers (not teenagers per se, but Sharwyn and Linu are definitely "pretty") to stop her. Along the way, there is much soul-searching (*cough* Aribeth *cough*), personal growth (*cough* henchmen quests, especially Daelan), and maybe a romance or two (PC w/ Aribeth, PC w/ Sharwyn, PC w/ Linu, [or PC w/ Aarin Gend if PC is female]).
Knights of the Old Republic? You're kidding, right? This is textbook. Darth Malak is trying to take over the universe. It's up to a ragtag group of angst-ridden teenagers (literally in at least one case) to stop him. Along the way, there will be much soul-searching (emphasis on the
much, especially the Darth Revan situation, as well as Bastila's fate), personal growth (the PC mostly, but also Carth Onasi and arguably Bastila again), and maybe a romance or two (PC w/ Bastila or PC w/ Carth).
