I managed to keep Jerusalem under control for quite awhile playing as the Scottish. But it is hard to fend off Islam. But my view on cheating, after about my 8th campaign i decided I was going to cheat as the Spanish and just rush through the campaign so I can FINALLY go to the new world. Well it started off that way i took all of what is now Spain, but I began to realize that the AI was pushing out some extremely large armies. I believe the add money cheat gives the computers money also, I have found myself in a 3 way war Spain vs Milan vs Denmark involving many many full stacks of units. So much for rushing to the new world..
