Seriously?
I keep my games in boxes anyway so it wouldn't make a difference.... I can understand you having a preference for uniformity, for instance on my bookshelves I like it when a particular series of books is all from the same publisher so that they look the same, but I don't obsess over it (so if I can't find a book from a collection that is the right edition, I will buy whatever is there)

Of course there is an alternative for you if you are really bothered, I believe there are a few websites which specialise in game covers for sale, like for Okami:Wii I think a lot of people complained Capcom put a huge review score on the cover-art (or was it the original Okami on PS2?) so online you could buy different ones to put in instead.
Or just make your own if you are handy with photoshop and have some shiny paper.
