True, and between my two re-plays, I did that to two different civs. But both times, apparently, the civ did not spend their faith on my nice faith buildings; and instead found their own religion shortly after I first converted them. And of course, that happens long before tourism starts to ramp up. So it was just a waste of early faith. There are plenty of targets for early missionaries, and getting WR passed is pretty reliable. But even at Prince, I do not think faith wars with founders is productive.They don't hate you if you convert them before they get their religion
In my first replay, I got all three faith Wonders. In my second re-play (and I expect the third replay to have this same speed bump, as it depends if Pacal founds or not) I could only get two of the three faith Wonders (and that was with shameless reloading) but I think I have my choice of which two. Of the three, I think Borobudur is the weakest.
