Despite beating over 40 games this year, I still haven't purchased a game that released in 2023. I've just been clearing out my library, and playing free stuff.
Of the free stuff that's come out this year, my favorite has actually been The Murder of Sonic the Hedgehog, with Pineapple on Pizza being a close second.
Of the games I've beaten this year, Half-Life Alyx wasn't just the best, it's the best game I've ever played and the runner up isn't even close. Although if we're excluding VR, A Short Hike probably takes the cake for best I've played this year.
