But the people stuck at level 13 don't actually have the game in their possession.
They have a bill for the game on the credit card they used to pay it online, yes. But basically it works like this:
1) Buy a physical copy of the game online, wait 3~ days for shipping and then start playing.
2) Buy a digital copy of the game, wait 3~ days for verication, but you can start playing act 1 content immediately.
Granted you can hit level 13 and kill the skeleton king in a matter of HOURS, but it does give you time to fully download the game (5 gigs? Which could take awhile for some connections) and at least try out the variety of classes to some extent before the rest of the game is ready. Which is more than you would do buying a physical copy that had to be shipped.
why would anybody -ever- buy a physical copy of a PC game online
