I happened to have on-hand 20 blank DVDs with cases which I picked up on the cheap a few years back but never used ([size=2]because, grr, I discovered my disc drive couldn't write DVDs after the purchase).
So I popped open Microsoft Word, creates a Slim-DVD case slipcover template, and got busy sorting, organizing and backing everything up to disc.
Here's the result:
Crummy real-world photo.
The backs of some of the cases are even more awesome, showing screenshot of the games.
