Clockwork Aquario Game Guinness World Records longest time between video game start to release

With the development initially started in 1991 and completed 2021, Clockwork Aquario takes over the mantle from Duke Nukem Forever that held the Guinness World Record title until now.

A story of true video game archeology
The initial development of Clockwork Aquario started in 1991. It was the last arcade game ever developed by the legendary company Westone. With the advent of 3D gaming and other genres vying for dominance, Clockwork Aquario’s development was canceled. Nearly 30 years later, ININ Games and Strictly Limited Games - two labels dedicated to preserving popular but also forgotten or never-released retro gems - joined forces to unearth this video game treasure.
