Day 9 - Saddest Game Scene
I'd have to go with the ending of Super Paper Mario here. After an entire game of background hints between what happened between Blumiere/ Count Bleck and Tippi/ Timpani, seeing them at the alter using the pure hearts in a way they know will kill them to save everyone else... so shortly after finding each other again... tragic yet beautiful. Not to mention the final scene following the line "May we meet again, in another time and place", with the two distinct silhouettes walking down a hill... I'm trying to stop the tears just remembering it all now.
