Played a bit longer (to ideologies, then the game started processing turns way too slow. I should really just play this game on small maps...).
Continents, standard, standard, immortal. Got a nice capital (used really advanced setup to give myself two fish), expanded quite fast, gold from expansion was almost always used immediately either for rush buying in new cities or for buying things in old ones. Or enacting expensive decisions. I founded Judaism (Semitic after all xD and Carthage likes monies), got holy law, stupas, synagogues, tithes, started slowly spreading. There was a time where I got the lead, I built several wonders, I even circumnavigated with an admiral from Hanno's Voyage... And then I fell behind. AI's cities grew like crazy while mine just didn't, despite me having Temple of Artemis. Carthage was growing at a much slower rate than AI cities, Egypt became a runaway. In late reneissance there were no more spots to settle cities, so that part of UA became useless. For most of the game my happiness was fine, later I started running into huge issues because of disorder, boredom and religious unrest, and even later ideologies.
Before I quit I planned to attack Egypt but just couldn't find a good time to do that as I was constantly behind. Also, not enough coal. Overall I found that I didn't have any advantage left later except for some gold from the UA and I felt like there was no way I could catch up with the AI. Probably done something wrong, but well...
Anyway, the new UA feels good in the early game, but it also says "expand or don't get anything - and sometimes you have to delay that expansion. Later, while the gold stays useful, there are no more good spots for cities, or there are no spots at all (because of the AI settling all the land, even ). Which means it stops doing anything lategame.
For the whole game I didn't build a single elephant, never crossed a mountain. I did build many quinqueremes which pretty much just explored and fought some barbarians, protecting embarked units.
