I generally differentiate casual and 'hardcore' gamers by how they approach games and gaming in general.
Casual gamers generally just hit up a game, give it their best shot, then leave when they stop enjoying it to go do something else. I.E: Load up CoD or something and just run round shooting, not really trying but giving it a good go, then getting not enjoying the game 'cause they got killed a lot and didn't get to do much, so move on.
'Hardcore' gamers tend to approach games more seriously. Not so much as a "I'll go on and give it my best shot" sort of thing, but as a "I'm playing to win" sort of thing. Didn't like what happened that match 'cause you didn't do too well? Give it another round and get better. In the CoD example above, go into the match focused, and trying to win, losing anyway and not enjoying it, but going in again to get better and win.
You can be 'Hardcore' for some games and casual for others, and you can be in between too.
That is, of course, if you give any credence at all to this whole 'Hardcore/Casual' thing, which really you shouldn't. Everyone is a gamer, and how they game, what they play and how good they are at that is irrelevant to be quite honest.
