Impressive!
I used to have a closet of doom at my previous address. I was the only one living in my mom's house at the time so I moved everything to the master bedroom and turned the walk-in closet into a closet of doom.I really should have taken pictures of it before I moved a few years ago but never got around to it.
At the place I'm staying at now, I've got a "Breezeway of Doom".My housemates have a ranch style home and I rent out the breezeway that's been converted into a room. Most of my stuff is boxed up with only a pair of Billy bookcases to show off stuff and a pair of shelves that have my DS and Saturn/TG/CD-I games. Everything else is boxed up in the basement. I'm trying to see if I can squeeze one more Billy into the spot where the DS shelf is.
I'm derailing so let me shut and get back to your closet....maybe you could add some more flair by putting posters or have an over the door rack for additional gaming swag?
