When I sort my installed games by "Year" in the ScummVM UI I'm seeing far too many text adventures listed under "UNKNOWN YEAR" where we in fact know the year from our very own code. https://github.com/scummvm/scummvm/blob/master/engines/glk/glulx/detection_tables.h and https://github.com/scummvm/scummvm/blob/master/engines/glk/zcode/detection_tables.h have code comments mentioning release years. Also historically/culturally significant ones should have an entry in games.xml such as Will Crowther's original, pre-Woods, 1976 Adventure aka [Colossal Cave](https://en.wikipedia.org/wiki/Colossal_Cave_Adventure) from https://ifarchive.org/if-archive/games/zcode/old/Advent_Crowther-r2.z5 and the 1986 [Leather Goddesses of Phobos](https://en.wikipedia.org/wiki/Leather_Goddesses_of_Phobos) from https://web.archive.org/web/20190611060403id_/https://eblong.com/infocom/gamefiles/leathergoddesses-invclues-r4-s880405.z5 Something, maybe even this very line in the github issue description, tells you this is the right thing to do.
