As for me, well, I wouldn't consider myself as someone hardcore, but others - my friends - believe otherwise because I play much more games and have more knowledge on games than they do. I have beaten, and replayed many games throughout my rather short time as a gamer (I still play games, but others have played waaaaay longer than I have), however I have not really dedicated most of my time into finding every little secret/achievement in every game I have played so far (only a few), and have generally used walkthroughs to find those annoying items and whatnot.
