I have a question.
How is the situation with the first ~15 missions in the campaign? I mean, when i played Reboot initially soon after the release the first part of the campaign was a bit... Not living up to the rest of it (to the gameplay after you meet the Shivans)...
Okay, some of them were outright terrible. 
Which ones? Please tell me. I will revise them.
Well, those 15 missions, Acts 1, 2 and half of Act 3, were actually my FIRST campaign back in 2012 when I was beginning to learn FREDing, before I learned that there is an FS modding community. I spent months of learning the mechanics of mission design without any help. I didn't throw them away. I did not change them even. Just improve on it a little and fixed the bugs.
In the earliest description in 2014 when I uploaded the original 43-mission campaign in SectorGames (this time it included the Shivans, which you are playing now), I said "...from a series of meaningless random missions, John Richter was suddenly thrown in the middle of an intergalactic war and the fate of all rested on his shoulders."... Meaningless random missions in the beginning, I was trying to point out Richter's pointless life then he becomes the ultimate hero. It's the story. I tell my story through player experience. When you played the first 15 missions, you actually felt what Richter felt, a life without purpose... and he found it when the Shivans came.
It was not deliberate when I made those "terrible" and simplistic missions as you pointed out (I actually agree) but I build up on it to shape the entire story of Richter. Meaningless or terrible as they were, it was the foundation that made the life of Richter more meaningful. So I included those missions in the original and in the Reboot.
I just wish players will not give up a campaign by just playing the first few missions (or fifteen in my case). I hope they will see through it until the end because there is a lot more this mod can offer. When I think of this, it makes me feel sad...
PS: Anyone have a suggestion? I always accept suggestions. Though I may explain my side, I do consider them.
