Sonic the Hedgehog Transitions

Pikuniku is an absurdly wonderful puzzle-exploration game that takes place in a strange but playful world where not everything is as happy as it seems.

Sonic the Hedgehog 3D is a free fan game about a famous SEGA mascot, Sonic, and it is made on Build Engine with additional EDuke 32 port. The game was inspired by two classic Sonic series: Mega Drive/Genesis and Sonic Adventure series.

Sonic World DX is a Heroes-style fangame with over 15 playable characters and 10 unique stages!

Sonic Advance Revamped is a remake and reimagining of the original Sonic Advance on the GBA using the Sonic Worlds Delta engine; it's a passion project designed to be the definitive way to play Sonic Advance, with better hazard placement, a 16:9 aspect ratio, patched-up levels and bosses, completely redesigned Special Stages, the smoothest sprites from each GBA Sonic title (with some special cases and custom sprites here and there), re-implemented unused/beta elements, and true classic Sonic controls to make the game feel even better. Features set for the future include an exclusive Team Chaotix Mission Mode, 8 Unique Playable Main Characters (7 of which are playable in this Demo), a fleshed-out Tiny Chao Garden, New Levels and Music Tracks, and more! For this particular Demo, Sonic's Insta-Shield is swapped-out for his Drop Dash! This move will be an early unlockable in the final version.

The game is an attempt at a mini-crossover with Sailor Moon, in which characters from that universe can be summoned by Sonic and his friends as helper characters with the use of Chaos Emeralds. It takes on an 8-bit Sega Master System style and is designed to look as authentic to the system as possible (I think).

A flash-based Sonic fighting fangame based on Super Smash Bros. franchise. It has some characters from Sonic franchise and a campagin mode.

Even for the mighty Pachacamac clan, just the act of survival is a day to day struggle, and everybody seems to know that they can't keep it up forever. In pursuit of a safe home, a lone shaman named Ichima happens apon the Special Stage - and with it, a means of realizing their dreams of safety and peace...
