Agreed, perhaps it's something to do with the cost of the serial codes for the games, just a thought.
Actually I think you'll find its more to do with having to provide a game with 100% storage and bandwidth
Say you make a game and make 1 DVD hard copy, that is 1 DVD, case and manual. Then add on the cost of shipping & shelf space until it sells. That is the end of the costs for you. You can figure out exactly how many copies you need to sell to figure when you start making a profit
Now, the digital version requires that you take a copy of the game, host it for an unlimited period of and provide a potentially unlimited number of downloads. The problem here is that because you have no idea how many you are going to sell or how many times your customers will download it you can't calculate bandwidth cost, and because if you even sell one copy you need to host it indefinitely you can't calculate storage costs.
This means that they have to charge more and to charge it for a lot longer in order to make enough profit for the system to survive.
I hope that makes sense, a moment of clarity in a very long and drunk day
