Why do PSP downloadable games cost more than the physical copies??

[Mr. J]

Ok, so I got my son a PSP 3000 and myself a PSP Go a couple of days ago. I looked on Amazon to see the prices of the games and what do I see, jaw dropping price differences. For example:

Resistance : Restribution ($13.79 physical vs $39.99 download)
Dissidia Final Fantasy ($19.99 physical vs $39.99 download)
Grand Theft Auto : Liberty City Stories ($16.76 physical vs $19.99 download)
Mortal Kombat Unchained ($11.47 physical vs $19.99 download)
Soul Calibur Broken Destiny ($18.52 physical vs $39.99 download)
Mortal Kombat Unchained ($11.47 physical vs $19.99 download)

These are just some examples and I know that some price differences are minimal, but come on. Sony doesn't have to pay to have the game pressed or anything...its a freaking download. Why does it cost so much. I'm afraid that I'll be putting my PSP Go on craigslist. Its just ridiculous!

I'm in no way bad mouthing the PSP, but I feel that the Go was actually a step backwards. I probably should've gotten a 3000, but the Go looked cool. I guess you learn from your mistakes!
