If you're a hobby gamer, you can break down mass market games. Stick with me here, this isn't going in a "These Games of Ours" direction.
The vast majority of it is stuff a hobby gamer isn't going to give two craps about. Maybe stuff you'd play with your kids, but anything "adult" would mean dumb party games and bad liscensed games to make a quick buck. Then there are those rare games like Heroscape or Buffy the Vampire Slayer or Star Wars Epic Duels that are totally accesible for the mass market world but manage to strike a big chord in the hobby gaming world, often becoming coveted "grail games" in years to come.
