That's looking pretty swanky, man! Quite the collection ya got there, too. :3
I was in a similar predicament. I had a separate room for my games & what-have-you, but the lady didn't have a space to do arts & crafts and such. After an evening of heated discussion eventually culminating into a panic attack, I calmly pitched the idea of giving up my room to her & moving my things to the living room (a more logical place for the TV, anyway). This ended up working out in my favor. For my birthday, she helped her stepfather make some wall-mounting shelves, so I could get rid of many of the behemoths crowding the space. The rest of the room's a mess, but here's what I've done with the shelves:
(The empty space on the middle shelf is for my Dreamcast, which I'm currently playing)
This is a WIP, and I've got more shelves coming with which to put up the rest of my games, and some more toys, so there'll be more pictures soon. Yes, it may be odd to have all this set up in the living room...but we fly our freak flags high.
