I like keeping media organized. For instance, when I tag my music collection I have two fields: (re)-release date and original release date.
Games get re-released too but Lutris only has one option. What year did Castlevania come out? Well it depends on which version you’re playing and in what language. Virtual console release? Well you should consider that too.
I suggest the release date field should be expandable. It should contain two options in one: Platform - Release Date Perhaps multiple platforms to one release date for simultaneous releases.
