I think these sum it up for me. I'm terrible and thinking "this might come in useful" and then demonstrating that it doesn't, and I've been trying to overcome my hoarding ways and just selling stuff I know I won't use: especially useful early in most games where money is tight, no point in just sitting on it as I normally do.
Oh, trust me, I have it bad. For example, in the Lucky 38 Presidential Suite, in my bedroom alone I had a guitar on it's own table by the desk, top hat, a few skillbooks, and golden gloves on the shelf behind the desk, 10k stacks of Pre-War money, random cigarettes, and lottery tickets in the desk, as well as Police Pistols. A chest devoted to unique/rare/modded weapons, a wardrobe for unique armours, a wardrobe for unique clothing. This is all just the left side of the bedroom, then on the right side I had a wardrobe for....something, dont recall what. A wardrobe for 5 sets of each Pre-War outfit (Clean only) and hats and suits. Then Benny's suit on display, and magazines with an ashtray and pack of cigs on the table in front of the couch. The game room was filled with all kinds of toys and kid items. The kitchen set up to look very usable.
Long story short. That floor was a monument to the glory of my obsessive compulsive tendencies
