So I've had this idea for a Sonic multiverse game where the games cross over with other Sonic universes. Here is my idea.
Open Zone like Frontiers, but with some stages that can be found around the open world.
There are seven dimensions to explore: Games (Central City), Sol Dimension (Sol Kingdom), Archie (Mobotropolis), Sonic Boom (Hedgehog Island), Sonic X (Station Square; it's different enough from the version from the games), the movies (Green Hills) and a new dimension created by Eggman.
In the game, Sonic and his friends from across the multiverse and even his alternate selves must stop Eggman from using the Chaos/Sol Emeralds from all seven dimensions to merge them into one dimension that he rules.
Sonic, Tails, Knuckles, and Amy are playable from the start, but Blaze, the Freedom Fighters, Sticks, and Sonic, Tails, Knuckles and Amy from Boom and the movies are unlockable (assuming this comes out after Sonic 4, movie Amy would appear) by doing minigames like the ones in Generations, although each character would have more minigames than Gens.
There would be a "Shadow multiverse" DLC, where Shadow and his movie self fight against Eclipse.
Just imagine how fun this game would be. Imagine being able to explore these locations. This is an idea I've had for a long time (Spider-Man: No Way Home is what first inspired it), so tell me what you think, or if there's anything you'd add.
