I'm with Kid Fenris - the rehashing is the SAME now as it was then, we just tend to look at the past with rose coloured glasses.
Those who decry modern games tend to dislike a specific genre (say FPS) and bemoan how everything is just another FPS, and then forget how many platforming games we saw in the 80s that were terrible because they happen to *love* platforming games.
Nothing's changed, our memories just ain't what they used to be.
