"With 'Sonic Lost World,' we're going to introduce new gameplay and enemies, which is always fun. In terms of Sonic and his friends, he'll have his same friends there, and I think there'll be some new ones as well. It's not a reiteration. It's going to be all new." - John Cheng, president and chief financial officer of Sega of America
As usual, the 'friends' bit always worries me. I don't know how much they add into the mix. Sonic, Tails, Knuckles...that's the group I can appreciate!
