PLATFORM
PC: 66
Yes, all 66 games I beat were on the PC. Most of them were played via Steam, though there were a couple that I also played on GOG. This doesn't surprise me at all. Truth be told, the only console I played at all this year was the Nintendo Switch, and I didn't beat anything on it. Perhaps next year.
GENRE
Action: 14
Adventure : 5
Fighting: 1
FPS: 30
Horror: 4
Puzzle: 4
RPG: 7
Top-Down Shooter: 1
Visual Novel: 1
You'll notice that this doesn't equal 66. That's because some were hybrid genres that fall into more than one category. For example, one game on my list was a Horror RPG, so it's counted as both a Horror game and an RPG. The main focus though were FPS titles, which made up the vast bulk of what I played. This will likely surprise no one. RPGs and Horror having multiple entries also doesn't surprise me. And Action/Adventure are catch all genres that represent a wide range of games, so their inclusion and size also isn't unusual; they're holding a lot of titles.
That said, I'm a little surprised at my Puzzle games. I enjoy Puzzle games, and I find myself turning towards them more and more. The thing is, I usually play them for free via websites instead of actual dedicated games. I mostly get my Sudoku games via browser, and yes, I still play Wordle every morning. So to have only 4 officially beaten Puzzle games is nowhere near the amount of time I dedicate to them. They're just not tracked this way.
Oldest Game Beaten: Doom (1993)
This doesn't surprise me at all. Most of the FPS games I played through were either updated releases of 1990s classic FPS or boomer shooters done in their style. I am what I am.
