Diapers? As far as I know, no. I’m much more happy not knowing for that matter.
Though some aspects of the hobby are cheap. It depends on the games you favor. Straight up RPGs are not overly expensive unless you compulsively consume, and you don’t really need to. Miniatures will easily blow the bank for those games.
Know one guy around here, who’s a successful software guy, and I believe he told me he had 14,000 miniatures. Yes, all those zeroes are supposed to be there. Those are the painted Warhammer types, not the cheap plastic ones.
Miniatures? Never heard of that aspect.
I must have been away by then, or my ex played other things (Magic for sure, and then there were little velvet baggies with something in them - I never knew what, chips, dice, who knows. Something clinky.)
But, yes...DIAPERS. He even packed baby powder for chafing. UGH.
Times must have changed.
