Pretty good. I once got about 5 Cattle - it wasn't start, it was like my 4th city - and that was about as good as I've ever done.
If you want to see the worst I've gotten - and possibly the worst EVER - search for "The cgannon64 Challenge". Its a savegame after a few turns, the Mongols, on a desert island with hills that can fit about 6 or 7 cities. And guess where the island is? In the middle of the ocean, out of reach of all other islands. And just to rub it in, the other continents are fertile and huge. And I'm stuck on this tiny desert island in the middle of the map, surrounded by great continents just out of reach. Its so bad, its brilliant, I could barely make a worse start myself...
