It's not an online app
"I couldn't help but notice how low the polygon count is, and no wonder, if everything is streaming to and from your Internet connection. Why doesn't Moviestorm just offer it as a stand-alone?

It's not an online app - the Internet access is only used to download the app and the content packs one time. After that, the web access is only used to verify your license and for updates. It is a stand-alone app.
