I have found great success playing Carthagenians on watery maps. Pretty much most maps have some large ocean or seas. Given that Carthage will likely be on shoreline, you can perform this Ancient Rush with lightning speed. Basically what you do is scout heavily all the shores you can noting any city with 3 or more tiles of sea access. Next, beline to 'Seafaring'. It takes very little research and probably will need it anyway to acquire sea resources nearby. You dont need to make any setters or extra buildings, just start pumping out lots and lots of Quinquiremes. Quinquiremes don't require any special resource, have a higher strength then a swordsman, move 4 tiles and are easy to produce. You will be able to take out an early city-state with 4 of them most times. If you careful , without loosing any of your boats. Keep your fleet together and healed and move form target to target - eventually controlling all the shores you can reach. This can be done extremely fast, setting you up for a nice classical booming period. I ve done that in multiplayer, and dont know if playing single player on diety will does the same trick given the Ai production bonus.
