I just counted even. In 2017 when I was in college, I completed 6 games :(. Lots of League of Legends though. My backlog only includes the current game I am playing or PS Plus games. Still want to play bulletstorm, Yakuza, and maybe Mafia 3 and Mad Max. But first all of Kingdom Hearts.
That's what I'm doing right now lol, going on a massive Kingdom Hearts binge, since the only games I'd played beforehand were the first two when they first came out, the first area in Chain of Memories on GBA, and half a playthrough of Birth By Sleep on PSP lol, I've told myself I'm not buying or playing Kingdom Hearts 3 until I've finished all the previous games.
