I know what you're saying CO but if we're talking hypotheticals here, even if it was just SW '77 that's no guarantee Lucas wouldn't have released a SE for the 20th, 25th or 30th anniversary and that SE could be the only version available to us today. Lucas would probably be just as equally unhappy with SW '77 being in his eyes incomplete as he is today. It's very possible he would be more fixated on trying to fix his little science fiction fantasy from the 70's without the other movies to focus on. And he would still be a very rich man.
Beside reading these boards I have very little discussion in my day to day life about Star Wars. I don't watch the PT, my only reminder of them is what is discussed here and the occasional talk about them with friends, so I can quite easily forget about the PT if I choose to do so. I don't know if I'd want to give up ESB and ROTJ to wish away the PT and SE.
But it would be a nice feeling though.
