Moores Law gives us an expectation that the computing power in our consoles, PC's and mobile devices will double every couple of years or so. Naturally game developers want to use all that power to give us the best possible game experience- so they use that new memory to the best of their ability.
Unfortunately, networks don't get faster at Moores Law, for example the UK's average internet speed has taken around 6 years to double.
Roger Walkden suggested we take a look at a sample game to see how each generation has changed the download time. Here are the results:
Whilst there's a bit of jumping up-and-down here- there certainly isn't a trend to shorter download times here!
