Not sure how far Classic currently is, but it just had small quests to open areas, such as the scarf one.
My memory isn't perfect, but I remembr the addition to that cave near york town and the railway remake, which added more quests and player activities. Some year (s) later, that city has been added with a firefigher house.
Aaaaaaaanyway, the point is that Classic wants to release more levels and activities, which turns updates slow (quality>quantity of time) and when it is released, it won't take long to finish it. Not even water diving toke long to get all items available. The problem are we players that already did everything and want more, mainly because we started early and did nost of the things.
But I do agree that it is disappointing to see story lines of possible updates and in the end, they disappear together with the NPCs dialogues.
