FF XVI isn’t even an RPG; it’s an action-RPG; it’s like Stranger of Paradise, but it’s much easier.
And while the PS5 was supply-constrained for about two years, the chip shortage that constrained the supply ended a while back, so anyone can get a PS5 now without having to watch for drops or winning the PS Direct lottery.
The only turn-based Final Fantasy games were I, II, III, and X. All other games, except for XV, XVI, and Stranger of Paradise, use a global cooldown.
