It's not that there's a lack of interest, but there's a lack of resources. You can make a crazy indie movie with very minimal resources, making a game, especially alone, requires a lot of skill and time and even then it won't be near anything you see selling for $60. 
  
Basically you need funding and people who fund you don't like taking risks. (which isn't because they are evil or bad, but because their purpose is turning a profit, not charity)
