Kind of, when you playing too fast, like completing the objectives without good preparation and you do not securing your suroundings, you are taking a risk of that enemy will suprice you eventually. Same as in the Witcher game. Without potions, you can fail pretty fast.
You are right, that it is good to build and research as much as possible from the start, but then you can also realize, you do not have access to everywhere, because mission will not allow you to take the certain resources if you do not complete any objective.
The maps are mostly designed like, you should not proceed too fast (like complete as much objectives as possible in 1 hour) but also, not to proceed too slow (more then 4 hours you are not doing objectives). Both ways cannot be good for you and you can end up with frustration, because you are constantly attcked by the enemy pirates or biters. This is why I created the difficulty levels.
Also, mission 9 should be one of the toughest. My mod is done with style of classic old strategic games like first StarCrafts or C&C games. Sometimes my mod will not taking you for your hand and you must find out for yourself, how to solve the problem correctly. Even if that mean, you will completely fail, because you focused on mass production and did not controlled your pollution, so biters evolved so much, that it is impossible to kill them with your current technology and it is even harder, when pirates comes to play with you. :D
I agree that the maps still need to be polished. I am doing that every month because of the feedback from people like you and I am glad for that. :-)
Even now I just thinking, how I setup the enemy research. Maybe I set it too fast, maybe is too low. Don't know. It is up to you to tell me what is happening and when is happening :D. I am mostly having feedback from people like: "We completed the missions and we want more missions" :D. So I expect, there are no problems and people beat the story missions without issue. :D
