Spice Geyser

Otherwise known as a spice node.

Creature Stage
Spice geysers are useless for everything except for Flight of the Bumblebee.

Tribal Stage
Absolutely useless.

Civilization Stage
This now has a use. Use your vehicle to create a harvester on-top the geyser for income, thus leading to a Sporebuck income. Spice now is a valued commodity and all cities want the nodes of the stuff to gain massive amounts of Sporebucks. No node, no spice, no money, no game.

Space Stage
This has MANY uses. Spice can be seen now, in more than just one color. It comes in red, yellow, blue, pink, purple, green, even the rare WHITE spice! Spice can be sold in trade routes and in trade menus with different space-faring empires, and UFOs will try to pirate your spice for their own uses. A colony cannot work without spice (First of all, how the bloody Spode are you going to place the Colony, anyways?). Spice values regulate the economy for the whole galaxy. A solar-system buyout is valued by how many planets it has, and which have spice, and how valuable is the spice...The list goes on forever. The geyser is forgotten. Only the spice.
