I agree it needs something, we just don't agree on what that is. I think the restrictions could be that something, but there a lots of other ways the could go or add on top of the low-magic idea if they decided that is not enough. If the included stronghold, mass combat, and kingdom management as part of low-magic greyhawk setting that would be cool too. i wouldn't use those, but some people would.Greyhawk has to do something. You can't sell fantasy on a map with some of the fantasy restricted without some kind of spice to jazz it up. That's just selling trust in the group to do the work in making up for the losses.
