FF15 was on the healthier PS4 and already many years ago. It sold 716k at launch according to Famitsu and 690k according to Media Create, less than half of the 1.5mil launch of FF13. FF15 never managed to sell as much as FF13 sold at launch, not even with digital. It had a 90% drop in it's second week.

FF7R is a remake of the legendary FF7 and yet it only sold 702k at launch according to Famitsu but definitely had a higher digital share than FF15 because of the lockdowns that had just started. It got a big boost in preorders as soon as said lockdowns started shortly before it's launch, otherwise, despite being a remake of the most successful FF game it would have had an even smaller launch. It also had a 90% drop in it's second week.

FF16 might have a launch of again half the size of the previous game. 350k would be by far the biggest launch of a PS5 game so far and yet disastrous for the Final Fantasy franchise.

Of course, Armored Core was gonna get in the mix.

Zelda ain't too far from the 400p tally with the regular edition alone !

I always forget how strong the well performers finish so I have no idea if it's likely that Tears of the kingdom will make, might make or won't make 600 total preorders.

Waaaiii ... I just looked at the price tag of FFXVI for the regular edition in Japan and it is a hell of a price tag considering the other releases.

I can't see how such a big tag price on release wouldn't hurt sales on release week for the most hesitant ones
