I heartily approve of a system that ensures that 1 resource deposit is not sufficient for all your empire's needs. A lot of wars & trade is often not about acquiring a resource you don't have at all, but acquiring *enough* of a resource to meet all your needs. For example, the US has sufficient oil within its territory to be represented on a Civ map, yet how much of modern politics is driven by the need of the US to acquire sufficient oil to meet its needs? In a Civ3 or Civ4 game this simply wouldn't occur.
That said I'm 50:50 on the variable sized resource suggestion. I mean, to extend the oil analogy, the US oil deposits are
small, wheras I'd say the oil deposits of the Middle East are significantly larger-something I don't think could be adequately represented by simply having multiple deposits in the Middle East. Still, I can see where Ahriman is coming from in regards to ease of play. If there was a way that different sized deposits could be done in a way that was easy for a player to see just from looking at the screen, then I'd be for it. Otherwise, I'd have to go for the gameplay trumps realism argument
