hmm, ive been playing the Yor (on Tough) because of all the recent Yor bashing and ive nearly conquered the universe, and my economy is booming, and i have well-developed planets, so... i'd say their fine, but that prehaps the AI needs to be 'taught' how to use them properly.Are you playing with tech trading on? It makes a massive difference. Tech trees with massive holes big enough to drive a Terror Star through still work fine when you can plug them with somebody else's technology. Otherwise. . . I'd like to see how you're booming the Yor economy. Only way I ever manage it is with lots of empty tiles, and every world built up to 16-20 billion population. It's doable, but I usually end up in the "getting by" rather than "booming" economy bracket.
Yes i have tech trading on. but im not really using many of the stock exchanges (i have a couple on my recently conquered planet, but i havent gotten around to changing those planets yet to make them fit in with my grand strategy).
I think the bonuses i chose (it was a while ago) were along the lines of Moral, pop. growth as high as it would go, and also some soldiering, i build the Ypr structure that gives a 20% econ. bonus (but is 1 per planet) on every planet and have a couple of charging stalks on each planet usually too, immense galaxy, with evrything on common, i think.
