So me personally as I work at a GameStop, I like to buy collectors editions on release and then turn around and trade the disc in while the value is still high. Then years later ill snatch the game up out of the $5 bin to complete it again. Some games make that a pain to do so. If there is interest this can be updated with pictures but here is my list of the top of my head of games that have different disc art in there LE/CE than the standard(NTSC).
XBOX 360- Call of Duty MW2
- Call of Duty MW3
- Dragon Age Origins
- Dragon Age II
- Forza 2
- Halo 3
- Madden 09
- Mass Effect 2
- Mass Effect 3
- Need for Speed Carbon
- Quantum of Solace
- Transformers the Game
XBOX ONE
Please chime in if there are others that I have missed
