Now I did not really play the old overworld, but I took a peak at the old levels and can say that it would TRUELY take a long time.

For one, not enough developers to convert on good time. If you want to wait a couple years for the return of outdated levels/things you have already seen, then try petitioning that to the management.

For two, there are thousands of levels with depreciated code and a lot would have to have to be rescripted to make it work with the NPC Server and to accomodate for the depreciated code.

For three, that time converting can be better spent making something innovative that Classic hasn't seen before.

I've said this before a bunch of times, I don't see why people don't listen =/. Also DC pointed out it's not these developer's work they are converting so there is not much incentive to finish it fast.

Edit: Also as far as I am aware, the old overworld wasn't a gmap but please correct me if I'm wrong,
