The average real time strategy
One of the other things that would be lost with the move to digital delivery would be the manuals and bonuses that we sometimes get with game purchases. Some games would be unaffected by this, for example the average first person shooter does not need really need a manual, while other games could be drastically affected. The average real time strategy or simulation game has a huge manual with tons of instructions. Sure these would be printable from the download, but kal online geons just is not the same. Would you rather look at either a computer screen or a printed copy, or a bound book on glossy paper? I know where my vote it.
