Resident Evil 4s attache case inventory is fundamentally and iconically entertaining as a Tetris-esque mini-game and therefore disbelief has been suspended henceforth. It instead became clear players didnt find it immersion-breaking if the protagonist had an invisible storage compartment on their person that could somehow carry fish, herbs, grenades, eggs, an assortment of firearms, and an RPG among many other miscellaneous items that would otherwise encumber them. Resident Evil has pretty incredible inventory management systems overall, but Resident Evil 4 easily takes the cake.
