I recently moved to Boston and began working my first full time job: Game Designer at 2K Boston. You may remember it as the studio which recently released Bioshock. Previous games include SWAT 4 and Freedom Force.
My favourite game of theirs was System Shock 2, because it scared me so much that I could barely play it, and when I did play it I would physically tremble with terror. Yes, I was much younger at the time.
