i wish to god we had more games that had some sort of arts cover on the reverse side of the "retail" cover.
Yeah, this would be an easy win. Publishers balk at printing four-color manuals anymore, as a waste of money. It would be a trivial cost increase to print two-sided case inserts as a compromise, and a gimme to fans.
If that were the case, Americans would just buy games with just a black label on the cover that said the game's title. 
This is one of the things about Gamestop that bothers me so much. They'll take the most f'd up games and slap them in a DVD case with that "official gamestop insert" that already looks completely ghetto, HAND-WRITE the title in the worst handwriting possible, sometimes adding personal notes such as "AWESOME" to encourage sales, and put it on the shelf for the same prices as a used copy of the same game with a near-mint case and insert.
The other day a friend bought a copy of
L4D (360, Asia) in Nipponbashi for 800 yen, different than the other mint-y copies which were 900 yen. The case stated that the manual was damaged, so he grabbed it. There was a single fold on the cover. One fold = imperfect... DISCOUNT IT!
Used goods in Japan are awesome.
