So this sort of defeats the purpose of Steam and having the games in your computer to install and delete as you see fit, but as anyone who prefers physical collections may understand, I've made it a goal to burn the backups of all my Steam games and place them in slim DVD cases. I purchased a set of clear slim DVD cases from LDBMart and they're perfect. They have that little pop-up button that makes the discs easy to take out but keeps them sturdy in place at the same time, and even clips for manuals should I ever need them (but Steam backups of course don't require them).
I've managed to fill half my collection so far and thought I'd share them. So far it's actually kept me from downloading more Steam games until I play the ones I have and spurred me to actually play them.
Out of all the Steam games I own, I can count on one hand how many I've actually played. So while I tried to make the covers as game-specific as possible there may be times where some of my covers don't make sense, but that's okay. I like them plain and simple with more artwork than text, so sorry if this doesn't appeal to you.
I know there's a slim DVD template around here, but I made my own to fit the LDBMart cases properly, and made the templates to have logos for DOS, Windows, Steam, GOG, and Mac games. I can upload that if anyone's interested.
It's a space-waster for sure, but I like doing them. Plus, I get to design the covers how I want--though they're by no means perfect since I started using Photoshop just before this project--and, because the LDBMart cases are clear, I can even print double-sided to add artwork on the inside of the case.
Edit:
"The upload folder is full. Please try a smaller file and/or contact an administrator."
It ALWAYS says this for me when trying to upload pics. Why?
