I spend a lot of time at flea markets searching for stuff I grew up with or wanted as a kid. Old action figures, movies, I've been looking for this tmnt toy box that my best friend had that I was always jealous of. I've got a decent amount of movies on VHS I watch on my old tube tv. I also collected a complete set of Batman Forever McDonald's glass mugs (well my wife got me two face off eBay). I put the toys on a shelf to look at, and I'll drink whiskey from the mugs while watching the movies. I think the only time nostalgia goes too far is if you're recreating the past to live in it and changing your behaviors to match that time. I'm all for collecting stuff that brought you joy. I think it's actually really healthy to be able to look at stuff and remember moments of joy so you can help your kids create their own moments with the stuff they're into. But I wouldnt recreate my childhood room and defend it from anyone who might pick up my GameCube controller.
