I'd say a big part of it is the sheer number of games the typical PC gamer has in his library nowadays compared to the 80's-2000's.
With the ease of purchasing titles on Steam and other online distributors the hardcore gamer will have hundreds of games in his library. It's really impossible for the average gamer to complete every game they purchase.
I probably have over 200 games on my hard drive right now. This is a mind blowing number if you think about it. Growing up I probably never had more than a handful of games installed on my computer at a time.
