I have been lurking on the fringes for years, and made an account today because I had to express something similar to OP.
You have created a thing of beauty here. As the threads of this great interstellar tapestry weave finally together, it truly is a wonder to behold. And to think that it's mostly the work of one man / two men, the grind it must have been, day after day, year after year, the self-doubt, the vision and ability to stay the course, to be in the final finishing sights now.
And to be told that this thing, this work that must have *** consumed your heart and soul - verily I tell you this work is a thing alive that breathes and lives and has a soul, too. A rare, ethereal thing in video games these days - big budget, yes, soul? No. You could have taken the core gem of this game, the combat, wrapped a few scripted missions with it, and made a fine game on Steam years ago and some fine money too. Forgettable, but fine. What you have created instead is a universe that holds within it all these other giant space games failed to do, the power to be immersed in a living galaxy and truly create your own story.
I thank you sir, and I am sure I speak for many others when I saw we will be overjoyed at this games release! Bravo!
