Getting mad Spore bucks at the start of space stage.

Do the required missions at the start. After that, perhaps do some missions for other races or root around some planets for artifacts and sell them, just enough so you get a decent lazer for your ship.

Now fly around and find a planet with creatures in the Civilization stage. The planet you want should have be at T3 level and have anything but red spice production, spend some time and find at least purple or pink spice production. MAKE SURE this is a creature in the Civ stage and not an Empire or they will kick your ass. Easy way to tell is that you can't contact them. Now fly to the planet, grab your trusty spaceship lazer and hover over a city so you can just barely reach the city hall of that city and start ruining thier shit. Thier turret defense can't reach you and thier ships can't harm you as you are close to orbit and they are only Civ stage (Cheap I know)

You WILL run out of energy so fly back to your home planet and get a free refill, fly back and ruin another city hall until all colonies are gone and voila, free T3 planet that you don't have to terraform. Now all you need is to buy 3 colony packs, plop them down on your new purple/pink T3 planet. Make sure you start filling in house, factory and entertainment buildings. When you place buildings, be carefull to place them to maximize the production of spice, you want to balance the happyness of the city so it's neutral and you should get around 108.x production on all 3 colonies.

Now bugger of and do something for a while, fly back and pick up spice and fly to another empires planet and sell that shit. You want to shop around and some will try to lowball you. If the planet you try to sell at produces the same spice as you have to sell they won't buy it for a good price so look at the spice colors of thier production before wasting time flying there.

Got sporebucks? Good, now go buy some upgrades. What you realy want is do the right things so you can buy an Uber Turret and a spice tank upgrade for your colony. With the Uber Turret and extra spice storage capacity your planet it safe from pirates and your production should be a 30 spice pr. 15 min or so. As soon as you get more money buy colony turrets for all your colonies, now nothing but the biggest empires or the Grox can touch your money maker, and that happens wery rarely.

I got 30 million sporebucks in a couple of hours using this stragety.
