It slowly becomes dead. Compare games quality nowdays and back then.
Few years ago I was finishing games in every possible way for example: Gothic II, Oblivion or Fallout. I finished campaign in CoD or Cod 2 like 1738124721 times. Now after finishing mw3 I regret spending money on it.
Back then I could buy a brand new game for 100pln ~25 euro there was a lot of free content like guides, artbooks, maps etc, now nearly every new game costs around 150-200 pln and all I get is a cd in a box and an option to get a DLC.
Also reviving good old games and totally failing at it as example take a look at Duke Nukem. Maybe it's just me or communites in games are becoming full of kids and flaming retards.
