What is the advantage of download PC games

With digital download distribution, you can access games without having to go to the shop and buy them, or have them delivered. You get the game straight away, instead of having to wait days. You also usually get a key so you can download it again in the future, so as long as you can remember the key you can always get the game again - whereas if a CD is damaged you have to pay to replace it.

Downloadable games are usually cheaper than games on a disc too, since they do not have to make a CD and print a manual.
