To be honest, that is not a bad idea. Every age we could have a new area to exolore in the NE (1 grid worth). Travel there from different areas every age. A pand tonthe west of seperamu, take the camel caravn TP to the new land. Multiple dungeons, uniquenresources, no build zones. The next age would have you take a pirate ship to a chain of islands (which would replace the western one). This would add variety every 9-12 months.
