So in very first attempts to return to GalCiv, I experienced notable red signs that may not scream, but makes me worry if the game treats me fair. I do not mean to criticize, but at the same time it is very important to be aware of some things that look weird. Here are few examples, perhaps followed by more in the future:
1) Anybody can become a resource god, by improving his previous mining tenfold. You just simply have to research Recovery in a few turns and improve your mining by 1 (!!!)

2) In turn 101, as age of war has just started, some unknown civilization turned to science gods and discovered Beyond mortality tech and is prepared for tech victory. A bit early, wouldnt you say?

3) As I live my casual raider life, my adversary's president happens to wonder around in the middle of my den. Undefended, with no any of his valuable planets anywhere near. I thought it was better for him to stay in his main base to drastically improve his production output. But who am I to know anything about strategy?

BTW I am using Gauntlets race mod. It is the only mod that I use and it does not affect anything mentioned above, as far as I am aware.
