In early 2024, I actively began working on achievements. I continue to do so, and my current goal is described below in this list.
My library has accumulated a large number of short games that can be completed in under 10 hours. I've stopped hoarding them and try to complete them immediately if I've purchased them, but for now, I only want to complete Triple-A games.

Saints Row: Gat out of Hell
DARK SOULS™ III
