1. Demolish all industry and commercial infrastructure on your base world.
2. Notice that you begin with a negative income, but don't freak out.
3. Increase housing on your base-world so that there's just enough to fill it up (25 total). If you didn't research housing yet, don't. Not useful for the agri-collective
4. Research 20 agriculture, and build as much agricultural infrastructure on your planet as possible.
5. DO NOT worry when you see the negative income.
6. Once you get 50,000 food units, sell it on the market for 1 credit lower than the current price. It should get sold quick, easily replenishing your stocks of money. Note: Don't sell all your food, otherwise your population will starve, resulting in a lack of loyalty.
7. From now on, it's a simple matter of selling food so that your money comes back.
8. You can easily make 5 million in the first day on RT. So now, you have stability.
9. Buy a few minerals that the collective use. You should have 300 terran metal, 100 red and white crystal, and 300 composite and rutile.
Shamefully lifted from my guide.
Also, try to get some borders (6 is ideal). Try using the sloop, pinnace, and galleon. Extremely good collectives ships.
Don`t hide in newbie protection... you might lose your planets if you`re not careful (the server only refreshes your PR every once in a while, so if you have too much population on your planet... then the extra might push you above 5,000 PR).
Aim for 800+ land planets. Very easy if you`re newbie hunting. Get rid of your homeworld once you got some nice planets, you won`t need the 500 land anymore.
Get all ship tech.
