Not just my mood, but I have different flavors of favorite.
In terms of nostalgia and all-time enjoyment, hard to beat Ocarina of Time.
In terms of pure “this game is so good”, may have to go with Red Dead Redemption 2. Truly a masterpiece.
In terms of most hours played, Civilization 6 at over 2000 hours.
Love this game. I’m going for 100% for the first time, at about 92% now.
I actually think Guarma doesn’t go on long enough. Should have been more exploring. Yeah it gets a little unrealistic, but a lot of the late game does (see also the prison break, the Pinkerton fight at Lakay).
But overall this game is hands down one of my favorites, and I really hope for another Red Dead in the future.
