The difference between Wii Sports and any FPS. My 4 year old sister can play Wii Bowling but an Xbox controller is far beyond her, so I think a "casual" gamer is a person who plays easier games that you can pick up and play whenever. Whereas "hardcore" gamers spend most of their lives in video games memorizing maps, strategies, controls, etc...
A "Hardcore" gamer is probably an 80's or 90's kid who grew up with 8-bit/16-bit games and has extensive gaming knowledge, a "casual" gamer probably just picked games up a little while ago and, like the latest episode of Extra Credits discussed, view "hardcore" games and gamers with disgust.
However a lot of people, myself included, use the term "Hardcore gamer" to put themselves on a kind of gaming pedestal and condemn casual games for ruining a medium that used to belong exclusively to us.
