Even one of the biggest releases of this year was a DLC to Elden Ring, which means the actual game is still a few years old

My guess is that Palworld and Helldivers 2 carried a good chunk of that time. I was going to mention Factorio Space Age, but it would just track time for base game. Satisfactory has been in early access for a long time, but officially released 1.0 this year as well, I wonder how that'd count.
