Sonic 2: Community's Cut
Parent game
Sonic the Hedgehog 2 is a side-scrolling platform game and the sequel to the original Sonic the Hedgehog. Players control Sonic as he traverses larger, faster-paced levels across West Side Island, collecting rings, defeating robot enemies, and pursuing Doctor Robotnik. The game introduces Sonic's sidekick Miles "Tails" Prower, a two-tailed fox who can be controlled by a second player. It also adds the spin dash move, a competitive split-screen multiplayer mode, and pseudo-3D special stages in which players collect rings to earn Chaos Emeralds.

What if Sonic Triple Trouble had been originally released on the Sega Genesis / MegaDrive, after Sonic 3 & Knuckles?
A multiplayer-only ROM hack of Sonic the Hedgehog. Two players select a character (one being Sonic and the other being Tails) and both battle it out to try to gain as many hits on Eggman. The catch is that Eggman only gets destroyed when the timer runs down to 0 (unless it's a draw at that time, then, it will wait for another hit). The player with the most hits at the end of the timer wins. The player can also win if the other player dies before the timer runs out (if respawn mode is off).
Tom has mouse-napped Jerry's nephew Tuffy and locked him in a trunk in the attic. You and your furry little buddy Jerry must dash, jump, and climb from the basement up through every level of the house to rescue him in time. Jerry's main defense is his unlimited supply of marbles. Pick up other items such as bubble gum, meat cleaver, cups of water, moth balls, hammer, invisible ink and drill to overcome the enemies and obstacles in your way. Make sure you outwit Tom whenever he appears.
Sonic Galactic is a 2D fan-game inspired by the Classics. Taking a more "Saturn" approach with its art direction, Galactic aims to be a sort of continuation to where the classics left off. Aiming to follow the classics, Galactic features new zones, brand new sprites, and a new character! This energetic mole is more than willing to join the team in their battle against Dr. Eggman! This has been a fan-game under the works for about 3 years, and is currently using Hatch Game Engine, an engine built from the ground up with accuracy perfectly replicating the classics.
