This is going to be an interesting post, for those of you who use the modding community or other wise, when I first started using mods perhaps a year or so after vanilla I noticed one big thing. Half of the stuff that was done by the modding community should have already been in the game on launch.
As an example Chimney's that show smoke during the winter month's, buildings that light up during dark and window's that you can see outside of shouldn't have to be down-loadable mods.
