Stock in Japanese games giant Square Enix has dropped by 30 per cent since the launch of Final Fantasy 16.

As reported by Bloomberg, around $2 billion has been shaved from the company's share price since June. This follows Square Enix telling stockholders that Final Fantasy 16 had failed to meet up to expectations, something of an evergreen statement for the Japanese company's smash hit titles.

In recent years, Square Enix has had a number of titles that received weak critical and/or commercial receptions, such as Marvel's Avengers and Guardians of the Galaxy, Babylon's Fall and Forspoken.

“Flooding the market with unfinished, bad or untested games is a bad move,” Tokyo-based developer Michael Prefontaine said.

“The company has overstretched itself on too many titles without proper oversight.”

Industry consultant Serkan Toto added: “Square Enix has problems with their games output. These titles get a 70% rating on Metacritic, are kind of OK and are just very forgettable.”
