So, die hard fans should remember that the original title of the second TRON movie was TR2N. Then it got changed to TRON:Legacy. I have searched all over the internet for any acknowledgement of this, but can't find anything. To me it seems like that name came from the TRON Legacy code you find in the TRON 2.0 video game. Its actually a very major plot point. This code was intended to be an update to the original TRON program. Surely I can't have been the only person to notice this. I mean, this has to be more than a coincidence am I right? 

This isn't something I just recently discovered either, I realized this before the movie even came out. It has bugged me that ever since then I have not seen anything that even mentions the fact that the name TRON: Legacy was previously used in a TRON game that came out 8 years prior to the movie.

Cool! Thank you, that is a satisfying answer! This is probably my favorite piece of TRON trivia. I have told many friends about the first appearance of the name TRON Legacy and it blew their minds! Now I can finally drop the idea that the whole thing was some sort of well kept secret conspiracy!
