My car works perfectly with multiples of 5, so I prefer that. But you guys wanna hear something really fucking sick? I played a game where the volume would increase with DECIMAL POINTS. And it was borderline impossible to get to a whole number. It was always 8.17 or something. The devs were clearly some kind sociopath. Anyway, I noticed in the last update they changed it to whole numbers, so apparently enough people explained that that sort of thing is just insanity.
