7. If there's one thing you could name of the main strong point of the game, what would it be and why ?

The computer AI. It thinks while you are making your move which allows it to form much more complex strategies than usually seen. We have also put a lot of effort to try to make the different difficulty levels feel like different levels of play. Usually, difficulty levels just mean that the AI is given more or less free money and such. In GalCiv, the AI plays more intelligently as you increase the difficulty. So at low levels it’ll do things like mindlessly throw ships against a fortified target or leave transports unescorted. At higher levels the AI actually plays a lot more like an expert player would.

 

Seriously, I feel like my AI is simply broken. As if it was playing on beginner's difficulty even when I crank the setting up to masochistic.

Again, now on masochistic, the enemies will just send loads of unescorted troop ships at me, while at the same time ignoring my fleets as they approach their homeworlds to kill them. Other nations declared war on me, only to send even more unescorted troop transports at me. They took the small planet next to my homeworld since it was undefended - and now all these transports just hang around next to my homeworld, doing nothing.

In terms of combat, the AI is near to non-existant for me.

Did you patch the game to the latest version?

That is, what is the game rev?

I see some of the troopp transport thing happening myself. However I never have an easy time of it. Seems that the ennemy ships are always a step in front of me and I never get to kill easy ships.

Strange that you do... 

Oh well maybe I am just a bad player

Maybe you are expecting too much. The AI is bound by a set of strict patterns, which, once identified will the Human Player a huge advantage, esp. in space tactics. You are currently experiencing these.

One of them is that the AI will value a defended world much higher than an undefended. Thus, he will almost everytime leave some ships in orbit, and these can be ships of any kind. Early on, it is constructors/colony ships - although there are probably resources/empty planets nearby. He's also having unarmed "Fighters" in case no ATT-techs are available to him.

Here you have the answer why your Troop Transport is not being attacked.

Later on these are real Fighters and he will leave them in orbit, all the while producing some more which he will fleet together near his planet. In times of war he'll use them to clear out your orbital defenders, followed by a round of Troop Transports.

In times of peace his armies will stack near his worlds and take down his economy because of maint.

Another AI "trait" is that his ship will be locked onto a destination, and this will stay unless the mission is completed or has become out of reach. That is, if a you e.g. leave a planet open for invasion, his Transport will head this way and you can easily shoot them down. This is so because the AI doesn't re-evaluate his decisions every turn. Because, if he would, you could easily use this for your own benefit to totally distract him from any strategy.

However, in any case, if you know how he's going to play of course this will give you an edge everytime, and hence, old and experienced players use this to artificially prolong the game, using their strategies to even balance the AI's.

btw, just add one of your slow warships to your Transport-fleets, they'll then all move at equal speed. Plus you can shoot down some more Constructors 

This is interesting, because this hasn't been my experience playing at all.  I play ToA, and tough difficulty.  The AI regularly builds a huge military and very aggressively comes after me and defends their planets.  They amass large fleets and defend their transport ships.

So...weird.  I don't know what to tell you.
