Being a collector, you always want those special titles. I tend to gravitate to the harder-to-find games that usually come with at least a good recommendation. Part of the thinking behind the Top 20 lists was to get others talking about games that would be highly rated, even if some of them were obvious.
The other side is that for many games, especially the harder-to-find titles, it's become a harder and harder decision as to whether to try and pick up a physical copy or just find another way to play the title. For example, as of this writing, authentic copies of Final Fantasy III are selling on eBay in the $85-$95 range. I bring this title in particular up because not only is it a very highly rated game, it's available on a multitude of platforms.
