So SEGA have released information about their newest installment in the popular series. "SONIC LOST WORLD" is a brand new exclusive 3D sonic experience that takes elements from Sonic X-Treme [A cancelled Saturn game] and Super Mario Galaxy. You will switch between 2D and 3D in this game. There are new enemies called "The Deadly Six" The engine used in this game is not the Hedgehog Engine that was used in Sonic Generations; It is a brand new engine. Now for the part no-one expected due to what happened with 3DS Sonic Generations. The 3DS version of Sonic Lost World is in FULL 3D Nintendo 3DS Nintendo Wii U So which version will you be getting? I'm gonna be picking up the 3DS Version over the Wii U, Purely for the fact that the Wii U is still pretty expensive and this game marks the first ever portable 3D sonic game.
