I'm doubtful that you can get a GP from Stonehenge early enough to lightbulb Theology before anyone else founds Christianity. I agree that if you can do this, it would make the plan more attractive. Although, if you're converting to Christianity, you're making everyone else dislike you.
I lightbulb theology all the time using GPs, but then I'm usually playing Monarch and epic speed and not Immortal. Does your comment refer to immortal and higher settings specifically, or all settings, or WOTM7 only?
@slowrider:
Do you not find it more effective to give catapults city raider promos and use them to pound down the defenses in a city before the main troops attack. My experience has been that if I do it this way, I lose about 2-3 catpults per attack on a city but the remaining cats get stronger. Also my main army stays largely intact and I don't lose any other troops, usually. Depends on the number of defenders, of course, but I'm assuming about 4 to 5 defenders in a city.
Anybody else care to weigh in on what's best, here?
