Silver Chaotix

Silver Chaotix is an idea I came up with when I found out that Silver the Hedgehog (originally of Sonic '06) became good friends with Espio the Chameleon (originally of Knuckles Chaotix, and also a senior detective of the Chaotix Detective Agency).

The inspiration behind it is that I though Silver and Team Chaotix are perfect examples of characters in the Sonic the Hedgehog series who never receive as much attention as they should, and who should have their own games.

The game itself would be a 3D action platformer with four main playable characters: Silver, Espio, Vector, and Charmy Bee. However, there will be times when you can play as other characters, such as Knuckles the Echidna, Shadow the Hedgehog, and even Sonic himself.

Story
The setting of the game is a place called Astral City, a large, bustling city not unlike New York, but well-known for having a brilliant view of the stars despite being a city. Silver often hangs around in this city when in Sonic's time period because it reminds him of his home, Paradise City, in that it is much more futuristic and advanced than New York is.

Astral City is also home to a massive museum containing the city's most important relics: the Crystal Meteorites. These are three very small, mysterious meteorites that bear the appearance of small stars, which is why they are highly prized by the museum as symbolic artifacts.

The game's plot gets underway when Silver hears an alarm go off at the museum while sitting on the edge of a nearby rooftop, and arrived at the scene at the same time as the Chaotix Detective Agency. At first, they suspect Silver of a misdemeanor, but then they see a figure running off in the distance. They attempt a pursuit, but find that they are too late, and the culprit has escaped with one of the Crystal Meteorites.

They soon find out from a witness that whoever stole the meteorite was an anthropomorphic animal, just like all the main characters in the Sonic the Hedgehog franchise, which leads the detectives to conclude that it must be someone they know. The Chaotix Detective Agency begins its investigation, and Silver joins them because he wants to help bring justice and peace to Astral City. From there, it's a race against the thief to close the case before all of the meteorites are stolen!

Gameplay
As I mentioned before, Silver Chaotix would be a 3D, third person action platformer, similar to the Sonic Adventure games released in the early 2000s. It would focus less on recent Sonic gameplay patterns of moving incredibly quickly, and using a boost meter to move through a very linear level. Acceleration in a given direction would be slower, and there would be many more options for movement.
