From the article, "The news that Grand Theft Auto V will be squatting on 8GB of my PS3′s hard drive due to a mandatory install stings. That’s a big chunk of memory! You folks with newer PS3s that have at least 160GB hard drives could consider that a mosquito bite, but those of us with HDDs under 80GB will feel that sting.
Yet, we should be used to this by now. If you have a PS3, you have to accept the inevitable mandatory install. It happens. It helps us build a bond. Besides, it isn’t like Grand Theft Auto V is the only game noshing on our hard drives."
