Newsarama had a press release from Warner Brothers saying that they're creating a Watchmen video game, based largely upon the movie, that will come out in 2009.
Here are the details: It will be available for the top tier machines: XBox 360 & Playstation 3, and will be an "episodic downloadable game based on the film."
“We’re bringing the Watchmen universe to gamers in a distinct episodic game revealing action and combat for a great overall experience for fans,” said Samantha Ryan, Senior Vice President, Production and Development, Warner Bros. Interactive Entertainment. “The filmmakers have been extremely helpful in developing the high-quality game story and we are working to match the outstanding visual style of the film.” The videogame based on WATCHMEN will go beyond the film and delve into the characters, rivalries and challenges in a mature action-brawler. The game provides gamers with visceral superhero combat as urban vigilantes Rorschach and Nite Owl.
I want the Watchmen movie to be good. I want it to do well in the theater. Do I expect those things to happen, well, I think it looks good from the trailers, but I don't know that it will be a blockbuster in the theater. I also don't know how true to the graphic novel they can be using the standard 2 - 3 hours most movies are done in. The game could also be cool. But if people don't have interest in the movie they won't have interest in the game. It will be interesting to see what happens when this comes out!
