I started simple by using a 12' X 12' spare bedroom to display my Nintendo games.
My main considerations were cost and complexity. I used 3" x 4" metal shelf brackets attached to furring strip boards that I screwed into wall studs to minimize the number of holes. The shelves were made from 6" wide dog-ear fence picket board. Typical cost for a 12' wall was $60 in brackets and $80 in lumber. Labor was free.

I first took physical measurements of the games to be stored to determine shelving height and decided that the top shelf of each wall should provide sufficient headspace for displaying consoles. Then I simplified the process by making shelving heights consistent along an entire wall surface, forcing me to abandon displaying my Nintendo collection in chronological order. The most difficulty I incurred was in failing to account for size variations of special edition games.

I was fearful that large blocks of game spines would be monotonous, so I attempted to intersperse limited/special edition cover art among the rows only to discover this made for a chaotic appearance. I now prefer to keep them separate and acknowledge that quantity does have a quality all of it's own.
At the same time I discovered that long rows of import kanji spines were both unattractive and mystifying. I achieved a more satisfying result by overlaying the cover art of some favorite import games over the rows of kanji titles while still allowing the number of import games to be seen in the background.

I managed to display all of my Nintendo games and most Nintendo consoles in a single room, but sadly few accessories and controllers.
This is the most accessible my Nintendo library has ever been and I'm satisfied with the results.















The Sega room will be my next project and I will take the experience earned from those two to tackle my PlayStation collection, which is orders of magnitude larger than this.
