An aestetic question, if you will: do you separate your "Greatest Hits," special editions, and other games with different spine artwork into different sets on your shelves? I personally keep my Dreamcast domestics grouped together, followed by commercial homebrew games, and then by imports, to keep their spines homogeneous. Lately I've been thinking of separating early "white spines" from later "black spines" though I think that may be taking things too far.

What do you all do? Keep those nasty green-bars from your regular PlayStation games or let them integrate? Avoid collecting them altogether? What about imports?
