Well this is a different definition of hardcore than what I'm used too which would be doing absolutely everything in a game, including it's toughest challenges. Or in the cases of MMORPGs dedicating large amounts of time a week in a relentless push to stay at or near the top of the pack.

I've never heard the term hardcore to describe someone who doesn't prefer certain types of games in one broad genre.

Which, on the former note, I used to be. I simply don't have the free time anymore though. Unless I'm really into the game I'll put it down as soon as I've finished it - and even that's a bit of a rarity these days.
