Not sure if these are bugs or items that still need some work, but wanted to point out a few things I have noticed so far.
-- DreadLords as an opponent. My first game and I ended up with the DreadLords as a regular opponent in the game, but they appeared to have none of the bonuses that make them a threat. But still have some of the 'special' characteristics. Their armies consisted of single troops, as opposide to thousands. You could not 'see' or spy on their planets. And no combat bonuses for their ships.
-- You can view opponents planets easily using the spy tool. Even on first meeting a race. But if you double click a planet, it comes up and tells you that you need a 'high' level of espinonage.
-- Planets that need advanced colonization techniques still needs some tuning. I didn't see a difference with the two levels of colonization. Also, I think there ought to be more difference between the various colonization types. Some planets should be easier to research the colony technology. I.E. Easy: Aquatic. Medium: Barren, Toxic. Hard: Raditated, High-Gravity. And then have certain type of special bonues with each type of planet.
-- Mega Event: I have only seen one, plague. However, none of the other races have ever bothered to research the cure for it, thus their populations are almost non-existant. And why are the Yor affected by a plague that kills organic creatures? I think that some events ought to have little to affect on certain races. Just to make it more interesting.
