I have a question about the Krak des Chevaliers. As far as I know, the current proposal is that it's going to give a free Castle in all of your cities and I was wondering if that's right. Historically it was built in Syria to make a strong fortress for the Crusaders to rest and plan their next move, like a base. But right now in Civ terms, there would be no sense building the wonder in hostile territory if as long as its effects are that of +1 free Castle in all cities. In most cases, I'm sure it would rather be built on homeland turf than where it is historically located to secure that the +1 Castle effect stayed in the hands of fellow countrymen and for that I'm sceptical whether its gameplay mechanics display its historical effects properly.
So, my proposal would be that it's a moderately-cheap-wonder-for-a-conquered-city to build, would raise the town's defenses by 50% (25% after the discovery of gunpowder) and only be built during war. I don't know how much thought there is behind giving KDC +1 Free Castles wonder effect but I think it should be made more practical and a strategic asset. There's a reason it was situated where it was, and for all I know it could be a regular Castle in Civ terms, auto-built by another Wonder with +1 Free Castles effect.
