There are two ways to classify gamers, by time and genre.
Time: The basic and easy to define archetype.
Casual: These gamers often log less than 20 hours of play time a week
Core: The bulk of gamers, the play usually between 20-30 hours a week
Hardcore: These gamers manage to log 30-40+ hours a week. I fit into this genre.
-SubCore: Gamers that would be hardcore, but are restricted on time, because of parental/
girlfriend/boyfriend
interference.
Lead: These are the gamers you see at the top of the leaderboards, and statistically, for most games, these people work less than 20 hours a week. for most games this is the line
you don't want to cross.
