I know that some new PS2 games cannot be backed up (i.e. GT4, God of War), at least so far. I'm new to the Xbox scene; is it the same with these games? I have/will have games like DOA:U, Jade Empire, SC:CT, Forza, etc.. and I'm wondering if they have impediments to copying, like dual-layers or disc checks or whatever. I like the idea of using a large HD to eliminate load times and play emulators/movies/etc, but I want to make sure the horizon is bright for burning. Capiche?
