I know I played a lot of Team Fortress 2 during Halloween, since they do cool updates in the month of October.
Undertale might be the game I play every Halloween tho, solely due to having badass skeletons. 
"Just for comparison Uncharted 4 was 20x bigger than Splatoon 2. This shows the huge difference between Sony's first-party games and Nintendo's first-party games."
