You're right. I do not comprehend. I have yet to lease anything long term, figuring it to be a maintenance cost trap that would shortly strangel me.
I think I will pause/abandon my current game and try something more like what you said. If nothing else, it will give me some experience so that I can continue this dialogue.
So, let me see.
1) Control-N over and over to get a 700% research tile.
2) Altairian, max Research and, I suppose, economics, but focus on choosing research trait and party bonuses.
3) Use the original Colony ship to grab one near planet of some value but build nothing on it. Let the miner do the fields at my home planet and then convert (lease) to a colonizer and colonize a third planet, but build nothing there either.
4) On Home planet, buy long term lease research buildings, though a different juicy bonus tile can be used appropriately. Sliders to max research.
5) Research ... what? Research improvements? I generally do planetary improvements then sensors to get the survey ships going, generally I have ion engines from the start, but not always.
6) In one order or another, charge down the diplomacy track towards the SCC, head for Evil and psionic beams, get a couple layers of miniaturization, and use probably the homeworld as the SCC site. Get trade for eco capitol and, I guess, eventually Denocracy for the Political one.
7) Milk Minors as necessary for cash, waiting as long as possible so as to have the better Diplomatic advantage.
8) Build cargo weapons carriers for SCC to fend off hostile AIs.
9) Now choose which path to take to victory.
Am I close?
