I don't have much of a display my collection is stored on one shelving unit, and inside and outside an old entertainment center, some of my things are a mess inside two plastic containers, my collection is stored and sorted by Genre in other words I can just grab a game right away and play what ever kind of game I'm in the mood for. This kind of setup keeps me from staring at my collection for hours in order to find something to play, I play whatever I want to play for example if I want to play a first person shooter I know exactly where to find one without delay.
I highly recommend more of you sort by genre instead of only sorting by alphabetical order, you can still sort by consoles but I'd put all genres in one area so you can find a game for whatever you are in the mood for. Also I have certain series I like to keep together like my Halo related game collection is all in one small crate, in order of story.
White cut out paper is in on my shelves and collection cabinets that tells me what kind of games and genres are stored where,
