The development of Everwild it would have been completely cleared after the ouster of Simon Woodroffe, the previous creative director. The new creative director, Gregg Mayles, would have decided to completely change the game, reworking the game design and general style.
This was said by a source of VGC, considered reliable. More generally, this is a confirmation of what Jeff Grubb reported, who thus explained why the development of Everwild is taking all this time.
Currently RARE would be aiming to release the game in 2024 under the guidance of the aforementioned designer Gregg Mayles, probably the person with the most experience within the studio and with a pedigree surpassed only by that of the Stamper brothers, the founders.
Mayles has been in RARE since the late 1980s and it is to him that we owe titles such as Donkey Kong Country, Banjo-Kazooie and Viva Pinata, as well as the recovery of Sea of Thieves.
If Everwild were released in 2024, it would have required ten years of development, considering those of pre-production. The game was announced in 2019, but has never shown itself in playable form since, with some RARE members throwing controversial progress messages multiple times.
