I agree with Kenovo on a new gmap and the concept of splitting the gmap up into distinguishable towns. For me it'd be a breath of fresh air at the least, iEra is all one city. And don't make the mistake iClassic did, make your towns have substance and don't fill all the available space with shops.
I think a big thing that needs to be considered when redoing the gmap is that not every building has to be a shop or provide a service.
