nostalgiarot 

A form of brainrot that is the hyper-obsession of nostalgic material with a conservative mindset of not accepting change and moving on from the past, even if the newer material is objectively better.

Person 1: "Can't stand new Roblox...I don't like these R15 avatars and these newer, complex games. This is why I only play pre-2013 games and have a blocky 1.0 avatar with no UGC hats. Everything about old Roblox was better..."
Person: "bitch can you shut the fuck up??? bro has a severe case of nostalgiarot"

Nostalgiabation 

Occupying too much of your time with nostalgia.

I was supposed to meet up with Tim in town, but I got caught up in nostalgiabation by watching old cartoons from my childhood. He waited in town for four hours, until he was kidnapped by a homeless man.

nostalgiacore

a segment of aging rock music that elicits longing or affection for the past, typically performed by an artist that has continued making music but is most associated with the era of their early or hit songs

Green Day's totally nostalgiacore now because I can only listen to their old stuff. Dookie makes me miss the '90s.
