As I am writing this we have 17 hrs 30 min til launch. Today I have had more bugs than in the last several weeks. I created a custom race and launched the game several times. Each time the text for my race's strengths and weaknesses was outside its box. The box is in the middle of the screen and the text appeared in the far upper left corner of the screen. Aprox 30% of the games I started the area around my ships and planets were covered in FOW until I moved a ship (not a big deal, but a little odd). I played one game until turn 11 when I colonized my first planet, the colonization event gave me enough points for my first ideology pick. So I grab 3 free constructors... only no constructors show up. I reload and try again, same thing. So I close the game, relaunch steam, and reload the game... same thing. No constructors. Another minor one was found in the battle viewer, I had two ships fighting 3 pirates. The first of my two ships was destroyed and for the rest of the fight the battle viewer continued to display my power as two ships and the same power level while the pirates ticked from 3 to 2 to 1 with corresponding drops in the power counter. Again, not a big deal, but buggy.
I absolutely love the game, I have already gotten two friends to buy it. I hope this is a wild success for you guys!
