Planet Specialization is an ability that you start out with. When you begin the game you are given the option of choosing your race and profession. Now you can choose to be specialized in one type of planet along with the race/profession selection.

Planet Specialization increases a planet type's production output by 50% but lower another type of planet's production by 25%.

Here are the starter choices:

1. Terra +50%, Barren -25%
2. Icy +50%, Volcanic -25%
3. Toxic +50%, Terra -25%
4. Gas +50%, Icy -25%
5. Barren +50%, Toxic -25%
6. Volcanic +50%, Gas -25%

And there could be other choices for the other types.

lol nice idea, but this is how i would envision the bonus system to work, by actually punishing you if you take what should be an otherwise good planet, that you might take... like this;

1. Terra +50%, Exotic -25%
2. Icy +50%, Crystal -25%
3. Toxic +50%, Demon -25%
4. Gas +50%, Irradiated -25%
5. Barren +50%, Gaia -25%
6. Volcanic +50%, Oceanic -25%
