Not a single game. The C64 at a friends house got me into gaming. I found my love for beat`em ups like Double Dragon, jump and runs like Giana Sisters (at the time i didn`t know it was a Mario clone), i played my first Lucasarts adventure Maniac Mansion. There where a lot of other games i really liked Turrican, Barbarian, Mafia, Outrun, Law of the West and others i have forgotten (damn i forgot the name of the shoot`em up with the helicopter and the jeep, sorry).
So this was the beginning of my personal little history about this fun hobby.
