The Nintendo DS game Percy Jackson & The Olympians: The Lightning Thief is the first of what is bound to be one trillion games based on the upcoming movie with the same name (which, in turn, is based on a book). While Harry Potter is getting the Lego treatment, Percy Jackson is getting what is labeled as a "tactical RPG" If that's good or bad we let you decide while you check out the screens that turned up today. We're not taking sides (go Team Potter!).
