Kacie's World Quest

Kacie's World Quest (also known as The Incredible World of Riddles: Kacie's World Quest) is an action-adventure video game based on the Kuboian animated Kantasy series The Incredible World of Riddles. It was released for both the Nintendo GameCube and PlayStation 2 in Europe on 6th September, 2002 before being released in North America on 22nd November that year. It is the second video game based on the animated series, after The Incredible World of Riddles: Kacie's Adventure.

Much like the previous video game in the series, Kacie's World Quest primarily focuses on Kacie, but also stars Tennet. It focuses on the two going on an adventure to save both their own world and Riddle World from Ghoto, a ghost who plans on turning all the living things in both worlds into puppets. The game received mostly positive reviews, with critics praising the fun gameplay, extensive amount of replay value and to representing the original animated series well, although some criticised the game for being too easy or complicated.
