Pen Pen Trilcelon - Sega Dreamcast

Kids and the young at heart are sure to get a kick out of the goofy Penpen characters. And controls are extremely simple: there's a general action button, used to jump while walking or to stroke while swimming or belly-surfing, and an attack button, which causes your Penpen to try to knock down a fellow TriIcelon contestant. These two features, and the game's cartoonish concept, make Penpen TriIcelon the most kid-friendly game available as of the Dreamcast's launch. --Michael Fehlauer

Pros: Colorful tracks with imaginative themes Simple controls Cons: Penpens may be too wacky for older players
