I have a plan to buy a Sony PlayStation 3 of 12 GB super slim model (not the modified one). Suppose, I want to play 25 to 30 games, not all at a time but one by one, since all playing at one time is impossible. Can I be able to play it? Is there any disadvantage regarding this? Please note that I would play games only and would not do anything else such as watching movies or playing songs.
