Hey, I recently rediscovered Civ with this mod. Amazing stuff, congratulations to creator.
The only major flaw I stumbled across in short time that I got to play it by now is (inherited from orginal game) strategic resources economy- if you don't digg them out, you won't get them. And with more strategic resources in RoM it just get worse.
Now, I'm no modder but I thought of simple (or so it seems to me) way to resolve the resources problem:
National Projects (if I get the name good- such as Manhattan Project and Internet in basic Civ4)
With each technology revealing strategic resourse comes new Project called "X trade" (Iron trade etc.). Projects allow any nation to build 2 new facilities. One for civilisations producing wanted resourse - granting income, and another for civs without strategic ore- giving city that it was built in access to resourse (for a modest fee obviously)
Since only nations owning the resourse can work on project it is a bit like in real world- embargo works only untill someone decides to sell the forbidden commodity. Also, there should be some kind of incentive to start the x resourse trade, so civ that finishes the project should get some prize. Maybe quasi holy city that gives gold for each x resourse trading post built by nations in need? (I have no idea if such thing is possible in games mechanic)
I would love to see the resourse problem solved in final RoM version (I have no hopes to play Civ 5 untill I finish studying and start earning, so I'll be stuck with this game for long

), and I think my proposition should do it.
I hope I post it in correct place, and if there already is good solution to the said problem (that is other, than placing a lot of strategic resourses on map), please implement it in new version.
Peace,
