 The Geo concept was described by the development team as similar to other platform games like Rayman or Spyro , and skewed towards a younger audience . When the concept was complete , the development team presented it to several publishers , who stated that they liked the idea but its geometry @-@ based core too strongly resembled " edutainment " , and that they were interested in developing a more edgy , adult premise . The Nintendo GameCube had been an early choice for hosting the game before the PSP was chosen .
