Ever since Sonic the Hedgehog pounded on a "badnik" for the first time, he has been nearly unstoppable. From dozens of video games, to several animated series, to even a couple of comic book series, he (like his former rival, Mario) has been immortalized in nearly all forms of media. Sonic's 3rd Genesis game proves to be one of his best adventures ever.

   First, the graphics. All I can say is...beautiful, simply beautiful. Every pixel gives off the exact imagery it has intended to. Sonic Team even was creative enough to try to visually imply the passage of time between Sonic and Knuckles' stories.

   The sound is amazing, too. Every ring chime to every "pop" of a badnik is utterly sublime. Also, the music is top notch and catchy.

   With the four character selections, extended stories, and the 14 challenging Special Stages, you'll be playing this one for a long time!

   The synopsis of Sonic 3 and Knuckles is this: After his "Death Egg" warship is blown out of space by Sonic/Tails at the end of Sonic 2, Dr. Robotnik ("Eggman") recovers it, but not before running into then-newcomer Knuckles the Echidna, Whom he tricks into thinking that Sonic and Tails want to wreak havoc on Knuckles' home, Angel Island in some way. Later, Sonic and Tails arrive to investigate the wreck when Knuckles ambushes the duo, stealing the Chaos Emeralds and starting the story. Now Sonic must fend off the Echidna, as well as stopping the good Doctor's WMD from re launching, all the while collecting the Chaos (and later Super) Emeralds.

   As a final note, although the difficulty gets steadily harder as the game goes on, it stays at a good difficulty.

I don't remember them calling it Sonic And Knuckles and Sonic 3 they was release separately and i like sonic 3 more then any of them .It' Awesome that the Genesis have 4 sonic games not including pinball and mean bean machine since those aren't adventure platform games.
