i have to admit that i really like the Imperialistic, i've more than one time managed to spit my early first 4-5 settlers out fast enough that i could make a lock so that the other civs had to travel a long way to get around me. giving me time to get my econ up and running so that i could build cities, without getting them in the way of relatively good areas... managed to get hold of a big enough area in my last game that i could build 20-25 cities without interruption due to enemy cities popping up
