Maybe it is because I am old....
When you bought a game back in the day....
It came in a box
and inside that box was a manual
And that manual told you how to play the game and how it worked
and it was good.
Then over time game developers lost the manual you could flip through and leave lying about
on your desk with notes scribbled on it, because the clever people invented files so they included it on the games install - usually as a PDF document or as a windows help file.
And now apparently they just don't bother making one at all...
Progress?
