After all, DOOM walked the same path. It recieved a Special Edition with a fourth episode that was much more difficult than the entire game and tied it in with DOOM 2's storyline, when the original game was standalone. And you can't get the Original version officially anymore, except for the release on XBOX Live, you must download a fan-made patch for it. So I like the Original DOOM and like to think of it as standalone, nothing else after it.
And I'll do the same with Star Wars. Thank you for clearing that up for me.
