I am always interested... I like seeing everyones collections. There is so much to learn.
I have a couple hundred console games, but I never collected or saved boxes for them... just PC games. I just buy inexpensive cartridge and disk games from eBay for low prices strictly for playing the game and not for the box art.
For handheld games like the PSP and DS stuff I only get cased games however. Going to stick with that. All my games for the Atari Lynx are boxed, but for the Game Boy Advance I only have a few boxed games, the rest are bare cartridges.

Anyway, when you get a chance I hope you put up images of your collection.
