Spore allows the player to develop a species from a microscopic organism to its evolution into a complex animal, its emergence as a social, intelligent being, to its mastery of the planet and then finally to its ascension into space, where it interacts with alien species across the galaxy. Throughout the game, the player's perspective and species change dramatically. The game is broken up into distinct "stages". The outcome of one phase affects the initial conditions and leveling facing the player in the next. Each phase exhibits its own style of play, and has been described by the developers as ten times more complicated than its preceding phase. Phases often feature optional missions; when the player completes a mission, they are granted a bonus, such as a new ability or money. If all of a player's creations are completely destroyed at some point, the species will be respawned at its nearest colony or at the beginning of the phase. Unlike many other Maxis games,Spore has a primary win condition, which is obtained by reaching a supermassive black hole placed at the center of the galaxy and receiving a "Staff of Life". However, the player may continue to play after any goal has been achieved.The first four phases of the game, if the player uses the editors only minimally, will take up to 15 hours to complete, but can take as little as one or two hours.Note that there is no time limit for any stage: the player may stay in a single stage as long as they wish, and progress to the next stage when ready. At the end of each phase, the player's actions cause their creature to be assigned a characteristic, or consequence trait. Each phase has three consequence traits, usually based on how aggressively or peacefully the phase was played. Characteristics determine how the creature will start the next phase and give it abilities that can be used later in the game.
