Wait! I have witnessed an even MORE shocking alternate ending for Path of Neo! Sadly, I was not able to get screencaps, but my trusty secretary Beulah was able to make an accurate transcription...prepared to be shocked!
[Interior of Zion]
WEEEEEEEEE ARE THE CHAAAAMPIONS...MY FRIIIIIIEEEEENNNN-(sound of record scratch)
[We are now back in the white room with the Wachowski...siblings.]
NON-TRANNIE: So...how did you like the blue pill, YOU FUCKING LOSER?
(Both of them cackle hysterically and high-five each other for several minutes.)
TRANNIE: And just think, my cut from your $50 will go towards a new butt plug! For me!
NON-TRANNIE: Well, I hope that actualizing your gun-fu fantasies for a few hours has filled the void in your meaningless, consumer-driven existance. Which, of course, will be followed by the cold, immutable, irreversible stillness of your death.
TRANNIE: Ooooh, that plug'll fill MY void, if you know what I mean!
(Laughter. Fade to black. Commence ten-minute credit crawl, backed by both siblings' nonstop laughter and hooting.)
THE END (of the franchise).
PS "Simulacron-3" by Daniel F. Galouye was the first virtual reality book/story/movie/whatever. Or so I've heard.
