This is the Legacy List, a list of games I'm sure I have owned and played from 1995 (when I first started playing) to 2016, regardless of whether they've been finished. This is a close estimate, not a definitive, accurate record.
I no longer have most of these games, but a 💽 indicates those those that I still own, or have procured a newer copy at some point.
List sorted alphabetically, by platform and generation.
General estimate: 120 titles
