Since I'm a gamer, aspiring game developer, and amateur filmmaker, I think this is a good idea. I, unlike most, have an apparently unique ability to be able to watch video game movies without feeling the need to constantly compare them to the source material, and as a result am able to enjoy things like the Residnet Evil films without being an elitist douche about it. And Paul W.S. Anderson has admitted in the past that he's an avid gamer, and that he played through the Resident Evil series before making the films and looked at them from a fan's viewpoint as well as a filmmaking viewpoint.
So he had both aspects to look through. Most, not all, but most of the people who complained that the Resi. Evil films were crap were either film fans who didn't understand the games, or game fans who were pissed off that Anderson came up with a unique and different idea for the story (namely, completely different characters, namely Alice and Matt Addison) and wasn't sticking to what they thought it had to be. And that mentality stayed with them even when old favourites (like Jill Valentine, Carlos Oliveira, or Claire Redfield) showed up, and they wouldn't even give Anderson a chance. An exceptionally hypocritical and unfair move on the so-called 'fans' part.
So what Paul Anderson says here, I agree with. I think that there is definitely scope for games and movies to be united, and he is a great bet to help that out. We saw Heavy Rain take a similar sort of concept, in a way, and that was at least moderately well recieved. However, again speaking as both aspiring developer and filmmaker, I do see some difficulties. It will be tough to break the old mentality that films and games are completely seperate and can't coexist as a unified artform (sadly, a mentality I've seen in this thread a lot, and exceptionally unfair and ungrounded, Uwe Boll's travesties aside). And it'll be tough to figure out a good way of being able to unify games and films, though again, Heavy Rain had a good crack at it that worked reasonably well. I guess only time will tell if what Anderson says can be justified.
