Forget sales numbers, I've barely heard anything at all about FF16. I didn't even know it had been out for like a week now. I'm not seeing stuff about it popping up on YouTube, I haven't seen any ads for it, and I'm only really seeing any discussion about it in this and the FF thread. Final Fantasy's one of the biggest franchises out there, so I'd think it'd be inescapable for at least a month. FFXV sure was.
I am 100% certain the PS5 exclusivity is crippling it. It's funny, the PS5 itself seemed to lose a whole lot of momentum right out of the gate due to launching during the reign of Her Highness Corona-Chan the First, and then the damn thing was effectively unavailable for years due to the chip shortage, and now the $500 price tag is increasingly uncomfortable in our shitty economy. And now FF16's out, but only for PS5, at a time when everyone else's thing is hotter than PlayStation. Xbox has Game Pass, Valve has Steam Deck, Nintendo has 6-year-old cell phone hardware that's never price dropped because they're unstoppable, and Sony has a bunch of wokeshit and also Final Fantasy XVI.
