I'm a writer so I've written some pretty lengthy scripts averaging around 120 pages. In fact thats the average length a standard movie is give or take. For video games its a bit more complicated as you need to script certain situations and dialogue for every possible outcome, so lets give the average game 240 pages give or take.

Heavy Rain doesn't follow either, instead they went with 2,000 pages. Yes you read that right, two thousand pages for a script alone. David Cage explains that the script is so big due to difficulties scripting all the possible decisions, differnt storylines, and trying to branch out every part of the game without going too far.

He also explains some details about the recent trailer, more about the game, and tid-bits about some other development points in his interview with EU PlayStation Blog. Check it out!
