Sadly I was too young to see the OT in theatres, but I remember the toys for ROTJ. Then when I was 6 or 7 I saw ROTJ on video, and about a year later I saw ESB. Then for some weird reason I waited another two years before seeing ANH.
I was mainly just into ESB as a kid, but when I hit about 13 or 14 (so around 1993 - 1994) I got more into SW as a whole.
