Also, he claimed it would take “half a terabyte” (although he admitted he couldn’t remember exactly). My computer tells me the total file size of the graphics of all generic non-siege land units is almost exactly 1 GB, including both standard and enhanced graphics. There were 35 civs when DE was released, so it would have required an extra 34 GB. I admit this is an underestimate, because on release the game used a less compressed graphics format – but even so, it would be nowhere near half a terabyte!
