This is going to be bad:
I hadn't played System Shock 2 until a month ago. After more than a week of fiddling to get it running I gave up on the game after dying three times in the beginning.
I hadn't played Deus Ex until a year ago and (similar to SS2) I gave up fairly close to the beginning.
Having never owned a NES or SNES I didn't have the pleasure of playing any of the original Final Fantasy's, Chrono Trigger, or practically any other game from either system until around four years ago. I have yet to completely finish a single one (though I got really close in Chrono Trigger before getting fed up with having no idea what I was supposed to do next).
I've been in three Cal-O clans for Counter Strike 1.6 (one was probably 1.5 or 1.4, actually). I've never advanced past one season with each because I usually get bored after the first four or five matches plus I've never been on a team which really inspired me to care (it's hard to care when your clan leader is four years your junior and sucks at CS).
I sat and watched my friend and his girlfriend play Viva Pinata for longer than I could explain away with simple curiosity.
During senior week myself and my male companions chose to play through Halo on the hardest difficulty in Co-Op mode which caused much anger among the female members of our house.
I maxed out the clock on Final Fantasy 7 and beat the last boss in 3 moves (Knights of the Round, Mime, Omnislash). Oh, and I copied and mastered final attack and Phoneix so every one of my characters was immortal just to be safe...
I played Age of Empires II with some friends and my AP Physics teacher during lunch breaks in high school. Some of the games took up class time and other students would enter the classroom to us cursing and yelling at each other as we wiped each other out.
I have played three text based games in my time; Archmage, Kings of Chaos, and Dark Grimoire.
In our first computer class in high school a friend of mine and myself finished the entire curriculum (three month class) in less than a month. We then went on to play chess every class for the rest of the semester.
In our second computer class a bunch of us finished the entire curriculum in a month or so and, with nothing to do, set up a Joust tournament.
I'm sure I could go on, but that's enough embarrassment.
