It could be, but I think they should adapt, independently by the space. Most of the pathfinders and also the warriors were running around like chicken and get slaughtered by barbarians. 10 less CS means only 1 more possible city for each civ, else its the standard setting. Brazil had only 3 cities after 135 turns and picked progress. In that state, most of the barbs were gone and there was room for 8-10 more cities. Morocco had an awesome start with 2 floodplain/incene, a plains tea and several lake tiles, but wasted its hammers for 3 pathfinder after constructing monument. Thats a huge penalty.
