Although the game will seem very familiar to Sonic fans,Sonic  Advanceis an entirely new creation that's been built from the ground up.  The gameplay, graphics, and sound borrow from the classic Sonic games on the  Genesis and are successfully translated to the Game Boy Advance. The game's  single-player modes are relatively short 2-D platform rounds--each run takes two  to three hours--but replay value is added through the game's various characters.  Sonic, Tails, Knuckles, and Amy each have different abilities that make getting  through the game a unique experience.The real star here is the game's link capabilities. The Chao Garden allows you  to raise your little critters and upload them to the GameCube via thelink cableandSonic Adventure 2:  Battle. Having one cartridge lets up to four GBA players compete in one  minigame. Gamers can play two additional minigames if each player owns a  cartridge. Although the single-player game is quite good, the link options give  the title tremendous value.The only notable problem stems from the series itself: There are still entirely  too many cheap deaths resulting from the title's high-speed gameplay. You'll  find yourself zipping along a level only to be hit by an obstacle you had little  chance of seeing, let alone avoiding. Ultimately, the only way to get past these  hazards is to memorize where they are. This minor flaw doesn't detract from the  game's excellent value, though.Sonic Advanceoffers a very good  single-player game and some of the best link options of any GBA title.--Raymond M.
