This is the best action game for the Playstation that I have ever played.  During the game, you play and Crash and his sister Coco.  Their goal is to compete 25 levels to get all of the crystals needed to defeat Neo Cortex.  For every five levels there is also a boss that must be defeated.  Defeating each boss gives Crash a new 'power move' that will be needed in upcoming levels.  There are also five 'bonus' levels in the game.  The levels have Crash and Coco running, swimming, flying planes and spaceships, and riding tigers, jetskis, dinosaurs, and harleys.  For an additional challenge, you can try to get the one or two gems that are found on each level.  This usually requires smashing all of the boxes found on the level.  For an even greater challenge, you can try to get the relic found on each level by racing thru the level under a specified amount of time.
