Research definitely carry over. And it is easily spotted: after having completed a tech, you will see that some research was put onto the next tech down the line. Just check after all turns events has been displayed.

Yep, it's me. Hi Pocus

I'm sure can only see the Grand Scheme (tm) and forget about this kind of optimization. But I will have to play at a lower difficulty level then...

the 'turns till completion' doesn't hold true at all. It says 1 turn, a turn passes, and the thing still is not complete.

Yes, that especially annoys me. Progress is listed as "turns to completion" - which is often wrong, to the tune of 3 consecutive turns listing "1 week to completion" - and cost is listed in "weeks". Why are the real cost and work until completion hidden? I mean, even if the planet management screen was fixed to display the correct time until completion, you still couldn't play effectively without a printout of "TechTree.xml" and "GC2Types.xml", since the costs of buildings and technologies are hidden from the user... unless I'm missing something. But in my one game, I always felt like choosing a building or a new technology was a matter of spinning a wheel or rolling some dice, since you rarely or never know:

1) How much a building costs (and thus, whether it is a good investment);
2) How much a tech costs (which is again the amount of BC you pay to research it, or its opportunity value when trading);
3) What effect a tech will have (since no description is provided for any of its benefits);
4) How a building will affect your planet (no known equation relates the final numbers to the stats of a building; the game doesn't tell you what the effect will be of a building before building it; and the game's list of which bonuses come from where is pretty vague AFTER building it. For example, what does +45% morale do? It doesn't raise morale to 45%, by 45%, or plus 45%... Will building a farm increase the growth rate? Is the population being capped by unhappiness, planet quality, or food... and will +4 food raise the pop limit by 4, or will the planet hit some other hard limit first? Etc.)

In other words, the lack of information prevents me from playing as an informed player, and forces me to choose between picking things that "sound cool" or alt-tabbing to the XML files every 2 minutes just to be able to estimate the numbers (which constantly change in unknown ways, as with technology, for example - the printed numbers are valid on turn one, and subsequently there is no way to tell how many BC you will spend to get a certain tech).

Thanks, I didn't notice the Civilization Manager before, since I only had 2 planets On the other hand, "Weeks Left" - even when accurate - don't let the player make rational decisions, since two items with the same number of weeks can vary greatly in their cost. Bear in mind that at a 100 research rate, a 101 BC tech and a 199 BC tech will each appear to be 2 weeks, but you spend twice as much on the second one.
