The suggestion is to add an option to sort Most Grinded Games by which has gained the most hours played in the past day/week/month.
I find myself returning to Galaxy every few months to see if any new games are being played A LOT. And while the Most Grinded list is the best indicator to me, it mostly stays the same over time due to evergreen classics. Occasionally, a hot new game will break into the list (such as Rejected Draft, which I enjoyed immensely), but it's not easy to tell which games are trending less dramatically. Apologies if this post should have gone elsewhere.
