I'd like to point out that one of the great things about older games is that they were simple. You popped it in and played within a few minutes. It's great finding a game you haven't played, buy it and then just play it. You add it to your collection and it's simple. Nowadays, you have to pop the game in, update for several hours and once thats done then you can play. It definitely requires a much bigger time investment.
Taking GT5 for example, there is so much to do before you can play, hours worth.
