Trade

Trade
In Spore, once you become a sentient species, you will encounter trade!

Tribal Stage Trade
In the tribal stage, you form up a tribe, but other tribes form up, too. If you have played the tribal stage on other planets and have been aggressive, other tribes may dislike or hate your tribe. You cannot perform music for a tribe unless they are ambivalent about your tribes existence or friends with you. To stop a tribe from hating or disliking your tribe, you must give them gifts. This is a primitive example of trade. Also, when you ally with a tribe, they also send you gifts, which is another example of primitive trade.

Civilization Stage Trade
In the civilization stage, trade will occur if you were industrious in the tribal stage, started as a civilization and chose your people to be economists, or you captured a city and picked it be an economy city. Once you did at least one of those things, you can click on a friendly city and click the option, "propose a trade route." Then, once the trade route is proposed, you can start trading with the city. The trading will earn you money and get you closer to buying a city. Some economic cities may offer to trade with you, which will give you money and if you trade enough, you can buy their city for a reasonable.

Space Stage Trade
In the space stage, you can start a trade route with any empire that is not at war with you. This will improve your relationship with them by a maximum of +30. Trading in the space stage is similar to trading in the civilization stage. You trade to buy solar systems. You can earn economist badges by buying solar systems.
