Do you remember your very, very first game you've ever played? I know for a lot of people it might be Super Mario Bros for the NES. Post the game, how old you were (or think you were) and where you played it/got it from.
My first was--you guessed it--Super Mario Bros.
I didn't have my own console until I was about six, but I remember when I was at Day Care, they had an NES. It was the Super Mario Bros/Duck Hunt combo. This is where I first learned how to 'cheat'. The rules were: Once you ran out of lives, your turn was over. They quickly did not count jumping on the turtle while it's going down the stairs to count.
It was great--up until one kid destroyed the NES during a tantrum.
