Apologies for so many topics of late (not that this place is busy), but Ive been away for a few months and there are a few things Ive been trying out in the interum.

Ive noticed a lot of people mention how their Kingdoms have a reputation that is "trustworthy", Ive never ever managed to get this no matter how nice I am. At best I get "Mixed". Is there some secret to this?

In my next campaign either as the HRE or France Im going to try and be the perfect Catholic nation. I may sin by accident of course (a general getting Winning First for example) but I will always do my best to atone.
The trouble is, how can you win the game being the perfect Catholic nation when you will have to go to war with another Catholic country at some time or another. I suppose you could have them excommunicated but considering that you have only 225 turns (or so) this might be quite a struggle.

So has anyone got any advice for being the most Catholic and Chivalrous empire on earth?
