First of all, let me say "Greetings, Programs."
I remember growing up watching the original "Tron", and the first time my family rented it from one of the video stores in my home town of Madison, Florida. And even after all these years, "Tron" still holds a place as one of my favorite childhood memories (including me remember watching "Knight Rider").
I recently finished playing "Tron 2.0" for the PC after I found it at Office Max for $7. And I must say, I was impressed with not just the game play, but with the story as well.
I myself have started to get into the whole concept of machinima (so far, I've experimented in machinima by using the video game "Need for Speed: High Stakes" and am currently planning and plotting out a potential machinima comic book fan fiction series set in the universe of the new "Battlestar Galactica" TV series on Sci-Fi). I've notice a few people here talking about using "Tron 2.0" to make machinima and I know how that there is a lack of programs to be useful in aiding in making such a machinima or in making mods (seeing that the game is a Disney related program, since when has the Disney company released a game that was a film tie-in that was capable of being modded?). Anyways, after doing some thinking, there are a couple of answers I can come up with.
1. Another program that uses the same engine: A while ago, there was a machinima maker who created a short film that was meant to be the start of a possible series called "Just A Game". The short was made with the use of "Tribes: Vengeance", which does not come with a editor. However, due to the huge fan-based for that game, a user who also owned a copy of "Unreal Tournament 2004", managed to edit and convert UnrealEditor (a program that is capable of both making maps and cut-scenes) over into a program called "Tribes Editor". And seeing that both games use the same engine, the conversion of the editor allowed the user who made "Just a Game" to make the "in-game" scenes. If the game engine for "Tron 2.0" has been used for another game (one that allows the use of the mods), then a conversion of the editor program from that game to "Tron 2.0" may be possible. However, seeing that I know nothing about programming, I cannot say for sure that the above is correct or 100% possible or plausable.
2. Another game with mods: Who said that using "Tron 2.0" HAD to be necessary for making "Tron" machinima? There are various users who have made "Tron"-inspired items, like this Tron-like glowing game character here: http://unrealtournament2004.filefront.com/file/Frost;65740
A lot of games allow for cut-scene creation, including the above mentioned "Unreal Tournament 2004", to which the two disk release of the game includes a bunch of tutorials on how to create cut-scenes within the editor. Though I know fans want to use "Tron 2.0" because of the in-game models already existing, using another game with mods, models and levels inspired by "Tron" with a game engine that allows mods would be a better way to go. Head over to Machinima.com , they've got many of examples of various game engines being used to make Machinima.
Now, I'm sure you're wondering what does the machinima have to do with a Tron movie discussion? Well, TBH, I think that if there is to be another "Tron" movie, that the should just be a remake of the story for the game. Instead of the normal CG backgrounds featured in the original, they could just use some of the in-game cut scenes for the "in computer" sequences (the only footage they'd have to reshoot is the real world parts and shoot it on normal film, so that they can establish the feel of both reality and establish the artificial feel of inside the computer worlds). I posted this suggestion over at the IMDb, but one user replied saying "That would look crappy." I still don't believe so. By using a gaming engine for the "in-computer" world, it would cut down on cost and time to create those sequences (in comwifes that cheat go what makes married men cheat
