I was also around in game when this was brought up. It was a great time and it was lovely seeing things like that be discussed in game with others getting together who don't go on the forum much.
I agree with these comments and I do believe the older maps should be implemented into the newer ones in some way, shape or form. This would bring happiness to the majority of the community as a lot want the same thing to come out of it. I don't have any ideas on how to do this as some good ones have already been stated, but I want to push this along again to the higher ups. I'm hoping one day something like this can be done for the community and future of the game. I feel this is one of the things that can really bring back a lot of the population.
