Homeworld



A Homeworld is the planet a species originates from, and is the centre of Empires. It is T3 (Or T2 and T1, rarely) and contains the same amount of wildlife & flora as any other planet. It has the same number of cities as when you end the Civilization Stage and the most relevant missions begin here. This is the only planet where you will find cells on, since you can play the Cell stage on it. It is also the first planet where you will find Natural Landmarks, crashed UFOs and Meteor Showers.

Cell stage
The player will start the game as a cell riding on a comet. The comet will crash into the homeworld the player has named, and the player will play this stage as a cell. This is the only point in the whole game in which you will meet Cells. After eating lots of food, the player's cell will be able to grow a (small) brain, as well as legs, and advance to the creature stage.

Creature stage
The Creature Stage is the second stage of Spore. In this phase, the player's homeworld will have hundreds of creatures on the planet, most grouped around nests. The goal of this stage is to either hunt them to extinction or socialize with them, from which the player's species will receive DNA points and parts. After the creature stage, creatures will gradually decrease in importance until they are little more than targets. This is also where the player will first meet Epic Creatures. The player can also come across Sea Monsters out in the middle of the ocean if you swim far enough. This is also where Rogue Creatures will appear. After the player's species' brain becomes large enough, they become sapient and form a tribe.

Tribal stage
In the Tribal stage, there will be fewer creatures on the player's homeworld. This is the only stage where domesticated creatures will appear. Epic Creatures and Sea Monsters will still appear in this stage, but in lower number. Rogue Creatures will no longer appear unless kept as pets from having them in your pack at the end of the Creature Stage. The homeworld will also seem smaller.

Civilization stage
This is where cities will appear on the homeworld. There will be even a smaller number of creatures on the planet. Epic creatures will still make an appearance. The player now will control only vehicles. They will either be a religious, economic or military vehicle that travels on land, in the sea, or through the air. The ultimate goal of this stage is to conquer all cities through Religious, Economic, Military or diplomatic means. Numerous tribes are displaced (the player can run over the huts with a vehicle), often after this, the tribesmen that survive can be seen gathering for a while. It's observed that they keep their outfit on when advancing to the civilization stage.

Space stage
This is where the homeworld will seem smallest. This stage is also where the smallest number of creatures and plants are. The homeworld will be a T-3 Planet and have a Moon like Earth does, but it may be different than Earth's Moon, such as having oceans, or lava. It's always T0, so it must be terraformed before it's habitable. The homeworld also has a ring system, which is speculated to be satellites orbiting the planet. The player cannot change to a different homeworld, as the homeworld is the basis of the saved game. If all the cities are destroyed then a new colony will simply be founded with no buildings except a city hall. The player is also unable to use certain tools, notably destructive superpowers on the homeworld. After recoloring the homeworld, a glitch can occur which when using the de-painting tool, where the planet changes to a completely different colour. This is the only planet that will recharge the player's health and energy for free.

Missions
Missions given to the player from his/her homeworld are different than missions given to the played by other planets from their and from alien empires. The missions the player can do for his/her homeworld are listed here:

Automatic Missions
As you progress, the player is given these missions automatically.
 * Explore a nearby planet, scan a crashed UFO and then scan a city's ruins.
 * Place a colony on a T0 planet.
 * Contact another empire.
 * Sell Spice to another empire.
 * Expand your empire to 3 star systems.
 * Expand your empire to 7 star systems.
 * Create 2 alliances.
 * Contact The Grox Empire.
 * Complete the adventure (Spore Galactic Adventures only).

Manual Missions
These are the missions that the player has to ask for.
 * Terraform a colonized T0 planet and put a Factory on it.
 * Paint a planet.
 * Find a Rare Artifact.
 * Sell a Rare Artifact to another empire.
 * Create a trade route with another empire.
 * Capture or destroy all the cities of another empire's planet.
 * Create an alliance with another empire.

Other Races' Homeworlds
All empires encountered in the space stage will have a homeworld. This is shown in the galaxy view by a filled in circle of the empire's colour. The homeworld of other empires will be T3 with up to 10 cities (usually fully fortified and extremely efficient while still happy) and can have any colour of spice. The exception to this is the Grox whose homeworld is T0 and only 3 cities. See the Grox page for more information on their homeworld.

Creating Homeworlds
This is a useful trick to obtain large quantities of expensive spice. Find a planet with the colour of spice you require. Terraform it to T3 and fill out the ecosystem. Next add a monolith and wait for the planet to evolve to space stage. You can then purchase the system via trade for a T3 planet with lots of turrets and 3 or more cities. Add a Spice Storage to store more spice. Unlike your homeworld, these planets will produce spice at a normal rate, meaning you can accumulate a large amount in a short space of time. Of course, these planets will not reap the rewards of free refills of health and energy for your ship.

More about the Homeworld
This section will explain homeworlds in the Space Stage.

Homesystem
The Homesystem will always have a Yellow Main-Sequence star. It will also always have the same types of planet. It will have a Hostile Planet (either Lava, Rocky or Ice) and is most likely to have Yellow Spice, a Spiceless T-1 planet where you find a crashed ship, a Gas Giant of any colour and with no moon, your homeworld, and its moon, which is a Hostile Planet that is most likely to have Yellow Spice.

While the homeworld is almost always in a green (habitable) orbit, it is very occasionally in a red or blue orbit, but it will most likely be T-3, but if it isn't, it's most likely due to a bug that doesn't fill up all of the slots for the Ecosystem

Trivia

 * The homeworld always orbits a yellow star, but is not always in a green orbit. However, this is not normal and it is likely to be a glitch.
 * The homeworld usually has red spice, but planets orbiting yellow stars can't have that color spice.
 * When choosing a homeworld, players can get strategic with their homeworld placement (such as choosing the closest world to the galactic core to get there faster).
 * If all cities on your homeworld are destroyed, a new colony is automatically added.
