maps are not just bad, they are very bad. never i restarted games so much as after this expansion.
worst is AI. they sometimes spawn in such locations, they are doomed to lose from turn 1. imagine pangea, inland and capital is between two lakes. capital is on 3 tile land strip between lakes, so when they found city, they have 2!!! land tiles to work. and some more after city border expansion. that civ make builder and that builder stayed idle for who knows how many turns. terrible maps. and those damned mountains... as if lakes were not enough to screw maps all over.
