I have yet to win a Prince game (giving up by 100 turns).
I do have a stubborn streak (very stubborn according to the peons in this forum), where I fight it out most of the time, but I do give up due to the following:
1) 5or more. (89% chance);
2) Last in score for 100 turns (96% chance) or second last in score for 200 turns (92% chance);
3) Getting DOWed by an enemy (AI or human) that is one era or more higher than (98% chance);
4) Be last in science (100% chance) or be deficient in the budget enough to lose half the original science (75% chance).
5) Start with 0 resources, or a total of 0 luxury resources. (100% chance).
I'm sure there's more, but you can obviously tell I have almost no tolerance to a losing game and will quit instantly.
Therein lies your problem. You give up too easy. I never had it that hard in Prince, but on King, most of my starts sound just like yours, the first 100 turns or more. Except for the 0 lux/resources- I play with abundant resources as default, so that's never been much of a problem for me. But if you keep building and working your tiles and fending off the aggressive civs, and making smart choices to improve your science/tech and military base, you'll eventually even out and break ahead, by the endgame. The key of course, is making smart choices along the way, from the start- if you just poke along and hope for the best, you gonna die, fo sho. The best way to learn what those choices are, aside from reading and studying strategy posts on this forum, is to keep playing, don't give up, experiment a lot, and take your lumps on the road to success.
Oh, wow- I look really good in this cheerleader outfit...
