@Rflong7 I don't know if I mentioned this yet, but I've been playing my Legacy Family Challenge with my Forsythe family in Glenvale County after my Sunset Valley save became corrupted during the 7th generation. The last time I played, the oldest of my 9th generation became a child. I currently have over 50 living members of the Forsythe family living in Glenvale County now.
I've only played in a few of the official game worlds. I played mostly in Sunset Valley and have other saved games in Appaloosa Plains, Dragon Valley, Moonlight Falls, Starlight Shores, and Twinbrook. I think I played in Bridgeport once, and never will again. I hate the elevators and am not fond of the vampires!
Edited to add: I guess that given what I've played, Glenvale County is my favorite world. My second choice would be Dragon Valley. Appaloosa Plains is third because the notifications are different than what I am used to seeing, although I do get tired of all the horses after a while.
