So I have not been able to get past turn about 250 or so on insane map but one thing that really a joys me is that way before then I have already maxed the ENTIRE Tech tree. It is rediculous and makes the game zero fun because now I am just pumping out maxed warships and steamroll everything and just lol noob at the AI. I remember in GC2 with my spending mazed it would take me 600 or so turns to max the tech tree, sometimes closer to 700 turns. Higher tier techs need to be made a lot more expensive. Anyway just my 2 cents.
