I enjoyed this book for quite a while, didn't finish. See below for reviews as I read the book, includes spoilers, so be warned: final score 3 stars, but 4 at the beginning.
Review at chapter 247: Interesting tech tree and method of growing a tech company despite economic pressure from the international community. The constant comparisons of which companies are involved in specific technology and material production is a little boring, and the story seems to drag and move slowly. The MC is smart as he builds an r&d facility, and when he produces products, he focuses on making components that he sells to others, or licenses technology. Because instead of making super products he makes components so his partners can make super products, he has a huge group of industry partners that support his research company.
Update after chapter 532: funniest moment in the book so far, MC uses complicated math to determine the 2 women after him will take 6 hours a week, or 17 hours a week, depending on who he picks, so decided he'd rather study than have a girlfriend. Second funny thing, needs cash to fund space research so gets into the health and beauty industry to get women to pay for it. Made 3 billion the first month. Aliens have also now entered the story, might be ok, might not, have to see.
Update chapter 672: 40 chapters to the end and I'm not enjoying the story as much anymore. He's out exploring the galaxy, and I'm just not interested. He left after he took over the Earth so he could have the resources to build a robot army to defend Earth from alien invaders. That wasn't very realistic either.
