Gamer as I am, I spent part of the last day of 2020 to grind out the last achievements in Farming Simulator 17, that was "supposed" to leave GamePass on 30th December.
It took some time, some planning, and checking some hints on TrueAchievements website, but I managed to complete the game before year ended and before the game was pulled from GamePass.
And apparently it was my 50th completed game (maximum GS per game) according to TA. Double woo-hoo!
