Yeah, that's not a good idea. Shared assets are a great plan, but it's a one-way street from film to games. That's it. That's all you can hope to do, because prerender is always going to be leaps and bounds more complex than real time.
First game was really fun. I'd say it turned me on to the God-of-War type of game, which I never got into because Kratos is the kind of lame ass, meaninglessly dark, violent, and macho anti-hero I'd expect to see scrawled on some pimply boy's Pee-Chee Folder in ballpoint pen. Starkiller is interesting, and the fact that SWTFU1 is "canon" storyline for the Star Wars universe made me happy in a way that the Prequels really, really did not.
