This is probably old news to most people, but I just noticed today that God of War (GH) has artwork on the back side of the cover art. GoW II does as well. My quick search of the forum didn't turn up anything about it.
Are there any other Playstation 2 games that have double-sided cover art like this? Too bad they didn't put these in clear cases, that would be sweet.
Edit: Doh! I just didn't search well enough. Looks like this is being discussed in the 'RPG list for PS2' thread. Mods, feel free to merge, lock, or whatever you like.
In case I decide to compile this all in one place, here is what came up in that thread (in progress):
