Ok so I'm thinking of Installing Fallout 3 to my harddrive and I'm wondering if there are any issues with doing that. Like would it be better to not have it installed or should I have it installed.

I,ve always found the game performs better when run from DVD.
Others have said otherwise. I suppose it depends on different things like whether the HDD is fragmented.

The only real way to know is to try installing the game yourself and see how it performs.

Well your 360 should make less noise playing from the hard drive!
