Ive given you plenty of reasons why it’s a useless comparison but you choose to ignore them and focus on a flawed argument.Previous released FFs games... I mean it is obvious... do you want to compare FFXVI sales with I don't know (chose any game here)?
So clearly you are not interested in anything other than if X doesn’t sell as much as Y at launch it’s sales are in decline if I ignore everything from install base, platforms, physical/digital split, FFremakevsMainline split, completely different eras (currently post pandemic and now inflation era) and on and on. The sales were and are amazing and people are enjoying the game.. that matters more. If you understood how box office works and perceptions you’d see that legs and enjoyment matters way more than initial numbers out the gate. Just look at cyberpunk… it did big numbers out the gate and then died quickly.
