Celeste: Just finished the story last night, absolutely love this game. This is easily a Top 10 GOTY contender for me.
Rocket League: Finally reached my Platinum reward rank, boy was that a grind. I wish you didn't need so many wins at the higher ranks to get your rewards, ended up falling out of Platinum twice during this run.
Fortnite Battle Royale: Loving this game more and more, blew this off for so long because I figured it was just a lazy ripoff of PUBG, but I was so wrong. Purchased the Battle Pass as well, definitely worth it if you play the game a lot.
Monster Hunter: World: I think this game is finally clicking with me, certainly helps the most to find a weapon you really like using, and playing with friends for not only the companionship, but also learning stuff from each other.
