i dont understand what do you mean by kiddy
when i was 13 i was more interested in playing Turok 2 and Resident evil
when i was 18 i was more interested in playing Super Mario sunshine and Zelda WW
Video games are mostly for kids, adults dont really have time to play much,

if you mean kiddy looking and themed, i wouldnt call it kiddy but appealing to every age group, including adults like me, and you...so not kiddy at all
