A few more suggestions for your covers, A-man:
- Use a different starfield on the front for each film
- Use different spine catalog numbers for each film
- Use different UPC barcodes for each film (I'd suggest something along the lines of using the original VHS/Betamax/Laserdisc UPC codes for shits & giggles)
- Use a different spine picture (other than just Vader) for each film
That's all I can think of for now. Maybe use OT.Com instead of Starwars.com for the back, as well?
