Rainbow Dash Gameplay: High speed action, get from point A to point point B.
 
Twilight Sparkle Gameplay: Get to the goal before Rainbow Dash, can utilize her teleportation spell to compensate for Rainbow’s speed.
 
Applejack Gameplay: Apples of Discord are scattered across a sandbox level, as Applejack you have to use radars and strong back hooves to find all three of them.
 
Fluttershy Gameplay: A Changeling has a beef with Angel for some reason, Fluttershy has to evade this Changeling if she wants to reach the end of the level.
 
Rarity Gameplay: Spike has been acting strange so it’s up to Rarity to try and fail to get him back.
 
Pinkie Pie (Or rather a Changeling clone of Pinkie Pie) Gameplay: Use your Party Cannon to destroy everything in your way.

I’d guess that each of the main 6 would have their own story and different style of gameplay.

“THE CITY’S BEEN FUCKING DESTROYED!”

Because it’s her hoof? Try comparing this to the actual Sonic Adventure cover, if you’re having trouble seeing it.

why does she have a dick and why is it so oddly shaped

Now we need a Rainbow Adventure 2 cover.

Dat Rainbow Team logo.  

I’d play the hell out of this. Adventure is my favorite Sonic game ever.

“All’s well that ends well!”
 
All has not ended well, you mentally defective chicken pony! The entire city has been crushed by water! There are billions of dollars in property damages! MILLIONS OF PEOPLE HAVE DIED A HORRIBLE, WATERY DEATH!
