It's a huge bummer that Steam has trained a whole generation to give up their right to own a game disc they can loan, trade or resell. And see it as a good thing because now all their games are in one "place".
If it goes missing, I will still have spent less than it would have cost me to rent it for a week back in the day.
Those problems also exist with physical belongings.
In a way, the lower price of Steam helped swallow the disappearance of the second hand market. I see the point, but wouldn't set it as a positive thing (neutral at most?)
