Mabe he had pure hunter-killer fleets? They don't appear in any attack list.

No, I tested and I can select one of all 24 enemy fleets. Even a slider appeared.

I have a bio-tech starship type planet (manual says I have to have starship level for starship type, but it is not true). I don' know penetrator technology. http://img690.imageshack.us/img690/9067/20120630201659001.png The planet is very bad designated, it doesn't produce any ships. 30% of the plane...

Now I think everything is OK. Selected fleet by F5 is selected, not visible, but still I can give it orders. And I forgot attack command always shows list of possible targets, so it should not be a problem to attack fleets that isn't visible on map. And 5 fleets in Windows Anacreon is better than 1 ...

It is DOS version and 2.0 but I think almost everything is the same in 2.1d. The .pas files are normal txt, you can change extension for easier opening and windows searching (ctrl+f).

I have two questions.

1
What is better for research
a) university on ruins
or
b) ruins and university separately

2
Does size of population, ISSP and tech level of university planet has an impact on research speed?

I was thinking about it and I started to look more closely at my battles. Here is what I have noticed: 1 My 30 bio-tech infantry vs 30 infantry on independent underground pre-warp planet (GDMs and fighters I destroyed in previous battle just for testing pure infantry battle). It was almost even figh...

In manual for DOS version I found: Less advanced worlds are always at a disadvantage when confronted by technologically superior forces. Even if the more primitive world is capable of building jumpships, for instance, the superior world will have jumpships that are somewhat more advanced. Troops wil...
