I remember sat in front of the TV with the silly-hot C-64 perched on my lap and being asked what the password was for entering the Black Market.
I don't recall if I got it wrong once and the guards attacked, or if it took a couple of attempts - but suddenly being outnumbered and out-gunned saw a flurry of keyboard clicks in order to survive. I managed it... just.... and grabbed a couple of leather jackets and Uzis for my troubles.
I also remember on entering the Black Market for the first time - just how expensive most of the kit was to buy!
Good times.
