2005 was the year I noticed it was becoming irrelevant. I had traveled thousands of miles to stand in line to be the first to see new games, and while standing in those lines, friends back home would text me talking about the trailer they just watched on the internet.
All those friends were wishing they could play the game as you were about to, though. It's not like pre release demos were that big (yes magazines came with CDs, but those were rare as far as I remember).
