Here's the thing. In order to do that, you'd have to download a shitload of data first to your PC. That, or, you'd have to have super badass internet. Plus the people hosting it would have to have a fuck ton of bandwidth and servers and so forth. See where I'm going with this?

Now consider how many people get Netflix and then rip the DVD's to their PC. Why is it that movies can be rented fully knowing that they can very easily be copied, shit there are even products legally sold to do such things, but PC games can't be rented because they can be copied? That's just bullshit. Console games can be copied too.
