Homeworld

Homeworld is a Featured Article

"Homeworld" has been featured, meaning it was deemed an article of interest by the Community.

A Homeworld is a T3 planet upon which a species has evolved, and, during the Space Stage, becomes the center of empires. Like all of their planets, the Grox homeworld is always T0. The player's homeworld has the same amount of cities that existed at the end of the Civilization Stage and provides the main missions which begin the player's journey across the Galaxy. This is the only planet where you will find cells on since you can play the Cell stage. (The only exception is if you create or download creatures meant to be cells.)

Stages[]

Cell Stage[]

The player will start the game as a cell in 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 gaining enough DNA, the player's cell will be able to advance to the creature stage.

Homeworld02 — Creatures leaving the sea.

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. When the Player swims out far enough into the ocean, a Sea Monster will appear and eat the player's creature. In this stage, Rogue Creatures will appear, and you will be able to befriend them or kill them (provided you have high enough attack/social points). 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 numbers. 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 fewer creatures on the planet. Epic creatures will still make an appearance. In this stage, the player can only control land, sea, and air vehicles. The player's vehicle type is determined by how they played the Tribal Stage. The ultimate goal of this stage is to conquer all cities through Religious, Economic, Military or diplomatic means. Numerous tribes are displaced on the planet (the player can run over the huts with a vehicle to destroy them). 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[]

Homeworld Space View — A homeworld, as seen from space.

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. The player's homeworld's moon is always T0, so it must be terraformed before it's habitable. 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 color. This is the only planet that will recharge the player's health and energy for free. It's to be noted that colony buildings have to be manually placed.

Missions[]

Missions given to the player from their homeworld are different from missions given to the player by other planets in their empire and from alien empires. 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.
Complete the Becoming a Space Captain adventure (Spore Galactic Adventures only).

Other 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.
Go to war with another empire.
- You will have to destroy or capture all cities in an alien system.
Create an alliance with another empire.

Characteristics[]

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. 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 color. 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 color 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 color 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.

Homeworld Statistics[]

Spice Production	About 10-20 units per hour with maximum happiness and buildings in all colonies.
Spice Types	Your homeworld will always have red Spice. The homeworlds of NPC empires can be any color.
Colonies	You start with 10 colonies on your homeworld (9 if you started in the Space Stage); however, they can be destroyed, and once destroyed they can not be rebuilt unless there are fewer than 3 remaining.
Vehicles	Your colonies will use whichever vehicles you want them to use; however, vehicle statistics don't apply in the Space Stage.
Buildings	Buildings in the Space Stage are the same as in the Civilization Stage.

Trivia[]

Red Orbit Homeworld — A homeworld in an orange orbit.

The homeworld always orbits a yellow star, but is not always in a green orbit. However, this is not normal, and is likely to be a glitch.
- Also, your homeworld could, very rarely, not be T3.
The homeworld has red spice, but planets orbiting yellow stars can't have that color of 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.
Sometimes your homeworld has a rare Cube Planet as a moon.

A saved game homeworld with the formations of a "Rock stack" storybook planet. (Note how the ground is smooth, and lacks the ridges this type of planet usually has)
Homeworld planets have a very slim chance to be a Storybook Planet. However, if it's the player's homeworld, there's a good chance it'll be missing a trait or two. In this situation, the game will not count it as a Storybook Planet, and it won't appear in the "my collections" page either.
Despite the Creature Stage having hundreds of creatures on the planet, additional creatures that are attempted to be added once in the Space Stage will instantly die since there is "no more room for creatures to be added."
Interestingly, using the Planet Color Reset tool on this planet will turn its air and oceans blue, even if they were a different color originally. This may be a glitch, or it may indicate that it was colored by another empire sometime in the distant past.
The homeworld planet can be considered to be about 830 meters in diameter:
