SW: TV in 1983. Dad taped it. I and my brother watched the tape often. On the tape before the movie was also a documentary about the depiction of space aliens in movies throughout the years, hosted by ET and Robin Williams (RIP).
ESB and ROTJ: I got the comic-book version of ROTJ as a birthday present in 1984, right when the movie came out in my country. Star Wars toys and comics was a big deal then, but I did not actually see any of the movies until on cable in 1990 or thereabouts.
TPM: Not available in my country until August. Saw it not the first showing, but within the first week.
AOTC: Midnight. Not the best theatre, but anyway.
HS: Video-CD at a Star Wars party.
ROTS: Second in line for tickets for the midnight showing at the best theatre and the very best seats.
CW "movie": Avoided when it was in theatres. Eventually saw it on the Internet or on the Cartoon Network years afterwards, I don't remember.
Rebels "movie": Not happened yet, but got an invite to a Disney event in a couple of weeks.
