I've noticed a few gameplay issues I thought I should point out.

The biggest is that the population growth ability, aphrodisiac, and having 100% approval ratings have the same effect on population growth: None. With or without any or all of these, as long as approval ratings are over something like 30%, the population will always grow by exactly 200M (0.2B) per week until the food limit is reached. Population growth and aphrodisiac say they affect this and don't, while the 100% approval thing is from the manual.

My second population problem is that, when I have tried colonizing poor quality worlds (4-6), the population stops growing well before the food limit is reached, even though my approval rating is 100%. For some reason, this happens when the population hits 2.68B.

Also, when I destroy a colony, its quality decreases by 2 points. Is this supposed to happen?

The Yor have two advantages that seem unbalancing, that other races can't even have. Miniaturization and higher logistics. Are they supposed to have these? If so, why? Is there anything to balance this?

When I set my industrial production to 100%, it doesn't use 100% of capacity. Instead, it uses, for example, if I have all spending categories set to 1/3, 2/3 of my manufacturing capacity and 1/3 of my research capacity. This doesn't seem right at all, and I don't remember it being this way in GalCiv. For example, if I have buildings giving me a total of 30 manufacturing points and 30 tech points and I put spending to 100% capacity, you'd think I'd be spending 60 bc, but I'd only be spending 30 (10 on military, social, and research). In a more extreme example, if I have buildings such that I have 300 mp and 3 tp capacity, and I split it evenly, I'll be using 100 mp on social and military, each, and only 1 on research!

Finally, I have a question. What causes Initial Colonies to change in Civilization Centers?

Thank you for your attention to these matters.
