No, it does not require such a map. Not if you play Pangaea or continents.
I play high culture maps (generally continents) and with the lower requirement for cultural victory on small maps (80,000) I found it impossible to get 1 city before entire Civ. I tried a few games at standard and could not get the city first. I did one game at large and again no go. it took the extra large to get the city first. I don't like large maps - standard is too big for my taste.
