Yeah, this isn't an inflation problem, it's a corporate greed problem. Prices have doubled for a lot of this stuff, sure, but quantities have halved, plus the little bit that's left is packed with awful tasting fillers. Money aside, why would anyone keep buying smaller packages of worse tasting junk food?
I'm still amazed that they abandoned the remasters of their flagship series and just left them broken. I think I'll hold off on any Rockstar remasters for the foreseeable future, hopefully it's not a bad sign for GTA6.
