To me, I can easily clock around 10 hours to a game if I really like that game. But again, different definitions for different people means to me that the term is completely meaningless if it's not unified.wombat_of_war said:being older than most gamers at 40 i got to see the whole gamer thing start and develop. all games at one point were casual games, they were things you can now find on your phone but you had people who were insanely hardcore with them. people who clocked pacman multiple times for instance.
hardcore to me means obsessed to a seriously negative degree
The better word you might look for is probably addicted.
