Maybe, but I'm going to look at it as in, tweaking regular, EA neighborhoods. lol
One thing that bugs me a LOT is the cemetery. I don't know how many of you have ever been to a cemetery but the ones I've seen or been too normally are not all raggy, messy and gloomy. And, since I really don't like ghosts moaning and swooping around my house, I wanted a lovely place to rest my dead Sims in. So my personal, favorite tweak is to redo the cemetery in Sunset. First I clean up all the trashy shrubbery, get rid of huge, hulking and/or dead trees and then I really go to work. I even move the mausoleum so there is room for me to make a ten generation grave area! When I'm done it looks more like a place you want to have a family picnic in, and I've noticed after I do that you'll find a lot more npc characters walking around looking at grave stones. Oh, and Grimmy goes on a "pedestal", (small island), right in the middle of the pond. I opt for the mood, "peaceful repose" when doing this. Maybe I just like large, public gardens.
