I realy love this series year ago and I still do ! they havent make anything that I be aware of that come close to these history base game . I will say that the other reviewer mention the xp mode on seven . I have seven and its the Home Premium and it do not have that option . I have find that if you change the setting on you display and disable explorer it seem to work ok . but the compatability mode suck ! color be off as it say . I wish they would make a seven friendly version ! so buyer beware no window seven for THESE GAMES IT look terrible ! other than that grab you xp machine , you internet connection , and you friend and have a all day marathon buildin ' and killin ' !!!!!
