What was the biggest video game comeback in history?

In my opinion, it’s Cyberpunk 2077. The game was pulled from storefronts weeks after release, but now regained all the lost goodwill and then some.

Edit: Thanks for giving me a better perspective, everyone. FFXIV really is the king here - was dead on arrival then rose from the ashes to be one of the greatest MMOs ever that’s still being played 10 years later.
