Back in the day most of a games backstory was relegated to the back of the box and the instruction manual. You played the game to reveal the rest of the story. To many games today make you watch the the main plot points instead of playing them.
Don't get me wrong, I enjoy a good story and glad to see games evolve, but I wish more games could use Bioshocks story mechanic. It keeps you in the game amd immerses you even farther into the world.
I guess what it comes down to is that I buy games to play, not watch. There's to many movies out there with much better acting and plots for me to sit down watch a game.
