No, actually, you are the definition of thick.
Seeing as you completely missed the point.
Who CARES how much space the game takes on my HDD?! That's not the discussion and you're calling me thick for not being aware of that? Jesus.
If it takes 9GB on the disk and 16GB on my HDD, then it will look like Crysis 1.
Following me so far?
Now, if it takes 15GB on the disk (HD-DVD) then it will take 30GB on my HDD and look twice as good!
