I wish my room was bigger.
I have a bookshelf toward the foot of my bed, a closet behind it, my brother's bed on the other side, a chair that has clothes hung over it, nightstand, drawers and some boxes that holds our games/comics. Posters rolled up, contained, and placed at a corner of the room, then another closet, more drawers and some other minor items about the place.
A couple bins under my bed that has old GB, GBC and GBA game cases (for nostalgia), and it also holds my various old artworks and comics from when I was small. Those bins are pretty much nostalgia boxes.
... It may sound like a huge room given all the stuff I have about the place, but it's actually really cramped. If I had a bigger room, maybe it wouldn't look like such a pigsty...
