How do you see a list of recently added old games? I want to see old titles that are added, but the store doesn't let me filter by just that, it just gives me new games too.

Is there a way to do this?

How old constitutes old?

Choose "browse all games" and then sort by "oldest first"

I don't think that would quite produce the results they wanted. Say ClockWerx was added to GOG. That was released in 1996, and setting it to Oldest would mean having to wade the river of time from 1980 onward.

The workarounds still seem to work, so depending on what your definition of old is, you may want to check out pre-2000, pre-2005 or pre-2010.
