@tante for many it's stuff they couldn't have when they've been kids.

Doesn't bother me.

Everyone should be happy with whatever.

When my Dad retired the first thing he did was buying a steam machine (no not one of Valve's) that he always dreamed of having when he was a kid.

I helped him restore it to "better than new" condition.

He had fun with it for an other year or so then he gave it away.

A couple a years later we did the same with a Train Set he also always wanted to have.

I neither care about Steam Machines nor Toy Trains and I don't like restoring old "shit" but I very much like spending time with my Dad so it was fully worth it.

A former co-worker of mine had crazy "Christian" parents so he wasn't allowed to have any kind of fun as a kid.

Now he has a giant collection of plushies and TTRPG books and is the GM for his kids friend group.
