I'm probably going to be going through the resources and taking some away. Mainly to open up space, and the other because I want to stimulate trading between 2 nations. Maybe make resources less far reaching such as limiting silk to China only.I can't do much about iron/copper/oil etc (resources that will be there without human intervention) but the more natural resources. Of course I'm not going to take TOO much away from places that need them such as Europe which has a lot of non-native plantlife, such as wheat and barley. I just want to open up space, and I can always use terrain now to substitute the food loss taking away resources might bring. Essentially I want to encourage Imperialism and Trade when that period of time opens up.
