No purchases since October... I've been going through some hard times with my father hospitalized from December to February and a difficult ongoing recovery at home, and then my country, Venezuela, is in such a crisis that the Covid-19 is just a minor problem in a very long list. Soooo.... no 2020 games for me.
As for games played this year, I got Flashback from the community giveaway (I rarely ask for games), so it was nice playing it again after so many years.
I also played Another World, which I've been playing more or less often since the 1990's.
My favorite that I played this year, though, is the Baldur's Gate series.
