Sonic Jam is a Compilation Rerelease of Sonic the Hedgehog games released for the Sega Saturn in 1997. It includes portsnote of Sonic 1, 2, 3, and Sonic & Knuckles as well as the Lock-On capabilities, meaning the full Sonic 3 & Knuckles, Blue Sphere, and Knuckles in Sonic 2 are also playable. Each game has some difficulty options which changes or removes some levels and there is also a option to enable Sonic's Spin Dash in the first game.
The game also has a short 3D level called "Sonic World", in which Sonic can complete a few fetch quests, interact with some items and enter some rooms where the player could listen to the games' music and view things like videos, concept art, game manuals and various bits of trivia, similar to the early Namco Museum games. Needless to say, it was the closest Sonic got to being in a 3D platformer in the 32-bit age, as Sonic X-treme was never finished.
Not to be confused with the Game.com Sonic Jam game, which is simply a collection of levels loosely based on some from Sonic 2, 3, and Sonic & Knuckles, and is regarded by many fans as the worst Sonic handheld game in history, if not of all time.
For the animated short featured in this game, see Sonic the Animation.
This game contains examples of:
- All There in the Manual: The strategy guide and in-game galleries had lots of interesting info about the games' stages and characters.
- Compilation Rerelease: Of previous Genesis games along with the Lock-On games from the Sonic & Knuckles cartridge.
- Concept Art Gallery: There's some artwork, advertisements, and full-screen FMVs for Sonic the Hedgehog CD. It also featured a promotional trailer for the Sonic the Hedgehog: The Movie.
- Easter Egg: By inserting the game's disc in a PC, four wallpapers can be found in the extras directory.
- Green Hill Zone: The Sonic World takes place in Green Hill Zone.
- Idle Animation: Sonic has a large amount of animations in "Sonic's World" for such a small game. He has almost thirty. Sonic Adventure reused a handful of the animations.
- Musical Nod: Sonic Pocket Adventure on the Neo Geo Pocket Color and Sonic Classic Collection on Nintendo DS use the music from Sonic World in their first zone and main menu respectively, which is something only fairly longtime and committed fans might notice (since Sonic's presence during the 32-bit era was limited to this, the Saturn version of Sonic 3D: Flickies' Island, and Sonic R).
- Museum Game: The game had an actual museum for Sonic to explore.
- Never Trust a Trailer: The In Name Only Game.com version had its footage sped-up in commercials. The actual game is very slow.
- No Ending: After clearing all missions in Sonic World, all you get is a credits roll.
- Screen Crunch: The Game.com version had assets taken straight from the Genesis Sonic games—big sprites and all. Because of this, you'll often find yourself taking a Leap of Faith, hoping you survive (or not, given the quality of the port).
- Updated Re-release: Contains the four main Genesis Sonic games with a few changes. Each game in this collection features Difficulty Levels: "Easy", which removes certain stages so the game can be beaten easily; "Normal", which changes some things with the level design and added some extra rings in some areas; and "Original", which plays as close to the original releases as possible. It also features a Time Attack mode, a Special Stage mode, a save feature for the games that lacked this feature, added the option to remove Time Outs, and in the case of Sonic 1, implements Sonic 2's Spin Dash as an option and restores the unused skid marks when Sonic stops to a halt when running.
