It's a valid opinion that you have ssj but it's a bullshit one. There will always be a market for kids games like God of War, so you can assure all of your classmates of that. All that the Wii means is that gaming is no longer a boys only club and that gaming can advance in a different way than graphics. For 15 years now girls and adults have been left out of the loop when it came to gaming. Now the Wii is finally giving them an opening. Games like Metroid and Zelda will never stop being made, it just means that you have to share. You are willing to share right?
Girls haven't been left out of the loop, most of my female friends love Final Fantasy and Devil May Cry. These games sure beat playing games about cooking or doing housework or whatever it is you think girls like doing.
