I kinda wonder how come this game is not in the database. It's a game from Ubisoft http://www.inmemoriam-thegame.com/gb/gam1.htm

From what I remember, you were like a detective chasing after a psychopath but he gave you clues in this bizarre games. After you completed them you then got a clue of the person you were looking for. It had also a strange way of using your real e-mail address in telling you the progress. Man, this was like the year 2000 or 2002 somewhere there if i recall correctly.
