Above question. I have discovered how to find games that I own published in 2010, but I was curious to see which 2010-published games I've played this year.
I don't know that there is a direct, easy way. It would be nice if the stats pages were shown with the same type of view as the user collection page, so that you could filter each section and customize the columns. But that's not how it works, unfortunately.
What you could do instead is view your games owned by year, and in a separate tab/window open your collection and filter with Own=yes and Played=yes (or omit the 'own' filter if you're interested in all played games). Then you can manually go through the two lists to find their intersection.
