Ok. Ive played for a while and its been good but i felt like i was wasting too much time on research so i was gonna fix that, i went into C/ Prrogramfiles/ Stardock/ Galciv2/ data/ english and open techtree.xmp (not sure on the .???) and changed the reqirment for each research to none and the cost to one, when i changed the cost to one for some reason (luckily) made it a reseach i already know, but then when i started the game i was missing lots of the reseaches and it was a pain but i checked again and its seems that most of the reseaches respond to cost =1 as already known but not all i would like some help on making it all researched
