I'm working on a fan game myself. It's very early in development but here's a preview: Sonic Legends - Lunar Paradise Zone
It's a game inspired by the Classic Series but with additional elements inspired by Sonic Adventure and Sonic Advance.
"Sonic and Tails fly away from Angel Island leaving the events of Sonic 3 and Knuckles behind, Destined for a relaxation session Sonic decide's to go to Paradise Island, A place where the grass is always green and lush and the stars shine through both day and night.
As the Tornado glides over the top of the fast flowing river, Sonic leaps off the plane and lands on the edge of a cliff. He faces Tails and gives him a farewell wave as the Tornado flies away into the distance...
Welcome to the Lunar Paradise Zone the start of the adventure. The start of the Legend."
I have an early build in the Sonic Dash engine but plan on moving to Sonic Worlds, I'm going to use Sonic Worlds Delta v.1.3 but what Extensions and version of MMF2 do I need? I'm having some problems opening the engine up.
