It was the THQ game announced at last year's VGAs. Oh come on — the one with director Guillermo del Toro heavily involved. Yes, that one. It's looking "really, really nasty" apparently.

But with the title not due out until 2013 (!), del Toro has talked up the complexities of game development in an interview with Wired.

"We're really trying a lot of stuff that I don't think would even fly in the movies," he said.

"With a video game, you don't have to solve one screenplay, you have to solve 20 screenplays, because you are giving the player the illusion of free will. If the character kills another character or destroys a building, the game goes one way; if the character doesn't, it goes another. It keeps you very nimble."

Another reason for the game's long development cycle is the fact that del Toro is working on the project alongside a movie called Pacific Rim.

"Up until the end of pre-production on Pacific Rim, we were still going up to Chicago, to Champaign, Illinois, to work with the developer. And every week we have a conference where we exchange ideas about the design, the gameplay, about the models.

"I'm taking it little by little. I think it's going to be a fun, scary game. It's a maiden voyage into the medium for me. I'm learning a lot of stuff."
