Ever play Nethack? It had events for Friday the 13th and new moons. Maybe full ones too?

It depends on your scale of dedication to exact definitions.

Holiday foods are deliberately designed to be nice subversions of pasty, but not something you would depend on (mostly due to rarity).

Dimensional Sundial is a reference to vanilla’s day and night differences, and could be seen as detrimental, depending on how you handle increased spawns. Also you choose to invest into it and don’t get it every time.

OG Pixel Dungeon had day-night spawn rate differences too. And I’m told DCSS has something affected by lunar cycles?

Not sure what the answer is, but SPD isn’t the only game that has this.
