Any recs for person who enjoyed HL Alyx (+ community mapsets) and Ancient Dungeon VR?

Currently 100% of my time is spent on games that are “six or more years old”, and a lot of that is spent on games that are more than 30 years old. But! I’m playing newly-made community content for 30 y/o games. This kind of retrogaming is something that evades Steam statistics entirely because it usually means playing custom sourceports of old games which rarely are on Steam. One old game I play on Steam to contribute to this statistics is Skyrim.
