Of course I always get curious. However, I'm not much of a roleplay joiner so I always have to sit and wonder at just how wonderful that map could be.
I have been part of a couple of mapped groups and I honestly enjoyed them when they were alive, but I have experienced often that when there are maps involved with a roleplay they would die out a bit faster then some other roleplays at times if there isn't a plot involved ahead of time and dedicated people who are willing to take the time to install the map. Being who I am I always expect a certain amount of detail among other things when I go into a map that makes sense for that specific roleplay, though I do become sad when those maps are no longer used and left in the dust. I also have seen many roleplays die because people are not willing to learn or ask for help when it comes to downloading maps, but a long time ago I have seen and I have done it myself where there were groups that did have a section in the main game map dedicated for their roleplay for those who can't download a map and then a map for those who can care and want to download the map.
Sorry for the ramble, just my experience getting the better of me.
