Ahh... I remember this thread.
Love Ady's stuff. Really excited about his corrections and tweaks to Empire, and loved his Star Wars. For me, I think fundamentally changing the ending if Jedi this way (and I truly think that is what is happening here) is a massive mis-step, and since he's always welcomed people's input so that was my 2p.
But y'know what, it's no big deal. I simply won't download his Jedi: Revisited, and I'll continue to enjoy his stellar work on New Hope and Empire and my personal canon will be SW:R, ESB:R and the original Jedi.
Or (as will likely happen), I'll edit the 2004 Lando/MF ending back into the otherwise tweaked ROTJ:R and have my own 'just for me' edition.
I think at the end of the day, no matter how much one disagrees with Ady on this one (and I really do), there's always a way to please yourself without throwing your toys out of the pram.
Oh hang on... screw that. SAVE NEIN NUNB! ;)
