>modern gex deals with his fall into obscurity
>he's old and fat, and spends most of his time making internet videos about how movies are shit now and were better during his time
>Gex receives a mysterious message saying an old foe is behind his troubles
>Rez must have come back and ruined all the video worlds, so Gex heads back in one last time to fuck up these trash flicks and make things good again
Gex just turns all the shitty 00's and 10's movies into shitty 80's and 90's movies, nothing is improved
Rez was the one who sent the mysterious message, knowing Gex would fuck up these modern video worlds without him needing to do anything
movies are ruined forever, but it's fine since movies were always shit anyways
