Hell Wiggy, why don't you just create some custom cases to store games in and tell us what the cost will be? you already know how to cheaply add sleeves to the plastic =D. We just need the cases.
Yes, I like the UGC's, however they are HUGE and take up way too much room. Since manuals don't "properly" fit inside them already, I have no problem switching to an alternative case. I would like to test these cases out, however I am sure that it's a lost cause on the NES's
