From igLoader website:
Quote: "Scalable architecture
igLoader scales. Through use of the Streaming, patching and branding functions the browser game is changing. No longer does a browser game have to be less than 5MB in size, they can now span Gigabytes. Titles normally reserved for CD or download only, such as AAA titles, can be downloaded and launched within a matter of minutes rather than days. igLoader will download, install and launch the files necessary to run the game and stream the additional content as play commences - simple!"
Also security for your games:
Quote: "Integrated DRM
The integrated DRM (Digital Rights Management) protects your applications from unauthorised copying and launches. igLoader encrypts your .exe files in such a way that it is not possible to launch the software locally, the software must be launched through igLoader and through the correct website for it to function. This functionality makes igLoader ideal in situations where games are made available to play through subscription or credit based websites. It also ensures the client visits your website to play thus increasing customer retention and advertising potentials."
