What's your definition of a hardcore gamer?

Anyone who is passionate and an enthusiast in regards to gaming.

The platform and types of games are irrelevant to that end.

What if it's just one game... or no game at all and just keeping up with the industry. Can one be hardcore if they aren't actively gaming or don't have the time but every few months they do a weekend of gaming or are they now casuals?
