One-source development - Game and Cinema.

Convergence between computer game and movies have been occurred since long time ago, but not until recently that it has been so dramatic and profound that nowadays it seems like almost it is something must-to-do. In these world, as Brookey puts it,

"Why is there no video game based on "Dark knights"? .... whatever held things up (game development) cause about $100 million in sales to be missed"

*In defense of the film (or lack of development of game), I believe Dark Knight was 1) almost too perfect to be translated into computer game 2) I don't know if a lot of people would feel right about playing a person or fighting against a person that committed suicide shortly after a movie, because he (deceased Heath Ledger) allegedly was so into a movie that he could not get over the depression after his role of 'Joker'
*Rest in Peace, Heath Ledger, you will be missed.

As Brookey describes it, one of the main reason that computer game was suddenly combined with movies was that movies are not making enough money to compensate, and therefore this one-source development has started to kick in. One of the reason, in my opinion, that the revenue of movies were decreased was that (not mentioning lack of good ones) people are now more used to play video games and they do miss the interactiveness they had in computer/console games.

Many early one-source developments were more often than not a failure; very famous example of E.T.,less famous ones such as Mario Brothers, Mortal Combat, Street Fighters, Tekken, and other names fill up the lists. So why now it is finding its market?

Many computer games/movies early on did not consider much about its contents being used in different platforms. Take for an example, a Mario Brothers. As Janet Maslin from New York Times observed, it was...
   "This bizarre, Special effects-filled movie doesn't have the jaunty hop-and-zap spirit of the Nintendo video game from which it takes-ahem-its inspiration..."

Nowadays, however, sometimes games are meant to be created, and other way around as well. In my opinion, Avatar, by James Cameron, was definitely one of the best example. As I was watching the film - as much as I was impressed and enjoyed its 3D experiences -, I can't help but thinking if this were out in game, how much success it would have.

And there lies my question for you: Which games would find success if it were made out to movie? and which movies would find success in game market?
