I remember the original Monkey Island being the first game I ever bought for PC! That being nearly 20 years ago when I was about 11/12... It took me over a year to finish it, as I got stuck twice, (use mug o' grog with mug, and key in cereal box) and had to get my cousin to tell me what I'd missed....
Later, I memorised the Woodchuck conversation from MI2, and annoyed many people by quoting it - lots!
MI3, the early internet era, and waiting 4 hours for a 50Mb download of the demo... then bugging the guy in the games shop until he got it in!
MI4... the heart-breaker. I never actually finished the game - I just couldn't get the hang of the controls

(I think it may be time to try again!)
