Regent isn't a challenge to win any more and I don't like milking either. (whats the inverse of milking???)
My intention was that this was just a bit of fun based on GOTM. Like Phil, I've enjoyed snatching an unlikely win from the jaws of defeat.
This 'competion' just extends that. There is an element of brinksmanship since if you do too well too soon, your score goes up. If you don't then you might not win! The worse things are going the better!!
Since your score is averaged over the game, I dont think abandoning cities late on will make too much difference. You will need to play out to near 2050 to avoid getting too much bonus - but that means stopping other civs winning. Its a whole new strategy ball game - and I figure that some of the inverse lessons learned will actually benefit my play!
One school of thought is that a OCC type game will give the lowest score.
We'll see.
Cry Havoc and let slip the puppies of War. Do your worst Phil!
