I bumped my post from Beta 3 but it has disappeared. The following is a way to excel your social productions on your planets. This was a problem in Beta 3 and still is in Beta 4.
Every turn you are given the option to buy out a social production (such as a farms, virutal reality centers ect.). The exploit is easy but really is beneficial once you start building expensive buildings (like Omega Projects).
Ok, here is how you do it. Build your social project, such as Invention Matrix or a Omega Project on a selected square (it will need to be at the top of the build list). Then on the right hand side pick a project that will cost less to build (like Basic Farms). Then click the buy button.
The system will build the 1st time in your build list inventory for the price of the Basic farm (or whatever you have choosen, the cheaper the item the better)
So now you can build anything for a cheap price every turn. Build Omega Projects for less than 300 units when they normally costs thousands and take many many turns to complete, you can complete this in one turn for just a mere fraction of what it would have cost.
If your wondering if this is useful when you only have 7 tiles to build stuff, the you need to read my other post (Under the name OnTheNaughtyList) about Exploiting your character attributes upon game start. You can easily give yourself 500% Planet Quality Bonus to allow your 1st planet to have all the tiles available to you, amoung other bonuses as well.
