I have problems where I can't make a hard interesting game. If I play fairer difficulty levels then I can have my fun early wars and rushes that I prefer but I generally win too fast. If I pick a harder difficulty then CPU units starting with Combat III shuts them all down and I have to play in a manner I enjoy less. High to Low games were fun for a while using TurinTurambar's AI which ensured that the last place was never hopeless. I should maybe try Final Five as well as civs vanishing would lead to an extended Settling period. Its also reached the point where I can't tolerate playing non-raiders civs for very long because war is so slow with them.
