Added a few of my own!
Favorite Game Played in 2021: Silent Hill 2 is my favorite game of all time and I played through again for I think the 7th (?) time this year. But that feels like kind of a copout to me. My favorite game that I played for the first time in 2021 has got to be Return of the Obra Dinn. Such an interesting, beautiful, unique, expressive, interesting, and engrossing puzzle game. It might be my favorite puzzle game of all time.
Favorite Co-op Game Played in 2021 I had the most fun with Stardew Valley, and have played about 80 hours between Steam and the Switch. I also really enjoyed Zelda Four Swords Adventures if you want something that's more story-focused.
Least Favorite Game Played in 2021: Last Blade 2. I just don't like 2D fighting games that much. More of a taste thing than anything, but I still had a really bad time playing.
Sleeper Hit of 2021: I would give this to Valkyria Chronicles even though I played it last year a lot as well. I'm surprised this series doesn't get more love. It was a TON of fun.
Favorite Pickup of 2021 For me, it's Mother 3. It was a birthday gift, it's one of my favorite games of all time and after emulating it years ago it's great to have the actual cartridge of the Japanese version. I'm considering diving into the game with a translation in hand which would be a bitch but that's how much I love this game, haha.
Favorite Gaming Moment in 2021: Finishing every single Kingdom Hearts Game outside of Melody of Memory. It took me about 240 hours over 8 months but it was a great accomplishment finishing the Xenahort Saga.
Proudest Collection Accomplishment of 2021: I recently moved in with my girlfriend and was finally able to display everything in my collection on a shelf for the first time since I started really getting into video games about 10 years ago. I owe it to her for being so supportive of something that I'm really passionate about.
