Graphics play a small part in games but they arn't the only thing that make a game successful the games you have listed above arn't only successful because of their graphics its also the gameplay and the story, it is true that Killzone 2 minus the good graphics wouldn't have been as successful, oh wait I was being sarcastic ofcourse it would have been successful its a successor to a previous game which sold enormously well. You are arguing that Graphics are the only thing that makes a game successful/unsuccessful which is a stupid argument.
Your stupidity amazes me the whole point of playing games is the ability to do things which are not possible to be done in real life, which is what gygabyte666 said.
Perhaps you should think twice before you use words like "inferiority complex" as when comparing gaming to life, gaming is definately inferior.
Console gaming will never be revolutionary the same thing can be done on PC with less effort.
I really don't see how a Wii is a compromise a Wii and a PS3 are almost entirely different devices, personally I would never get a Wii its a subpar console fitted with sub par hardware and a gimmick (motion sensing), which seems to be nintendo's philosophy and they make a killing doing it.
