Over the last couple of weeks I've gained:
A Wii U with Mario Kart 8 and Xenoblade Chronicles X
Dragons Dogma Dark Arisen - PC
Trine 3 - Artifacts of Power - PC
Resident Evil 0 - PS3
I think my concentration shall be Xenoblade with some RE 0 but first I have to get my son out of the game room. Also finding time is now a huge issue given that I have all this work to do for the new job plus I'm working as an independent consultant for the school board. Well it sure beats the alternative.
Yay for the backlog! It's how you know you're really alive, man! 
I've already managed to curb my spending to only games on my wishlist and am gonna be only buying games I wanna play right then. I can't buy games as if I have all the time in the world any more. Like you, I prefer being busy anyway. Speaking of which, back to syllabi edits.
I've slowed down my buying for 2016. Like you, I've got more than I can really play.
131 steam games what the hell is wrong with me I have tons of games on my ps3, 360,and ps2 and now I'm getting a new laptop for tax time my Christmas lol!!
And I'm turning 50 in March statistically I couldn't play a quarter of them completely lol!!
Adding more items onto Mount Backlog usually happens with a new console purchase. I'm not a Xenoblade fan but it seems to be a favorite among quite a few folks so it looks like you picked a good game to occupy your time with.
