Sonic X-treme is an unreleased platform game in the Sonic the Hedgehog series. It was originally developed by Sega for the Mega Drive/Genesis but was moved to the Sega 32X and eventually to the Sega Saturn and intended to be released around Christmas of 1996, but after many problems and a long hiatus of development hell, it was finally cancelled in 1997. Had it been finished, it would have been the first fully 3D Sonic game and the first original Sonic title developed for the Sega Saturn.
Sonic Skating is another very interesting skating game, here you have to help Sonic in his adventure and reach the endpoint in each level to complete it and to unlock the next. Use arrow keys to skate on various challenging tracks and press space bar to make sonic jump when it's needed. In each level you have to be very careful to avoid obstacles by overcoming either by jumping over them or just by moving in safe place. In each level there is a target to achieve, once you achieve the target by collecting required number of coins you will then qualify for next level.
