I think for a huge majority of the hardcore gamers, not many of them acgually pay much attention to the indie games. Two of my friends, who are both big, big gamers had never even heard of Super Meat Boy or Fez because they are both already so into the mainstream games like Halo, Borderlands, Assassin’s Creed, and Resident Evil.  I do think niches exist in the video game world too though because there are still people seprated by those who only play Xbox, those who only play PlayStation, and even those who only play on the PC or Mac.  Then thereare thoss niches seperated by genre such as sports games, first person shooters, racing games, strategy games, etc. And finally there are those hardcore fans of specific games such as Halo, COD, and Gears of War and the people who hate the other games so much and completely bash anyone who plays them. Indie games are probably the smallest video game nichd of all and it is still pretty hard to tell whether or not it is growing or getting smaller.
