Hello there,
I was a fan of GC since... Well... Since Master of Orion 
... I have to say I have fun already with beta 1 - homewer I found one very serious bug.
The bug reveal itsellf when you are building ships in your shipyard, and you have a que already. When you try to purchase a ship in this situation it will be build next round BUT credits will not be paid from your credit pool.
I hope this wasn't posted before. I checked the forum a little bit but I have to go to work now.
Have fun playing GalCiv!
