Given Chris's total lack of creative thought it would probably be the game Sonic Adventure staring Sonichu with pokemon training, a free roam CWCvile, and a possible dating sim in which Chris woos boyfriend free girls, beats up Jerkops who try and stop him and maybe he has to beat Mary lee Walsh in a guitar hero match.
It would basically be an ego driven mess, trying to cram in every element, set piece, and character from Sonic the Hedgehog and Pokemon that he remembers to plagiarise, all the while trying to have a game about his chaotic combo and be life story about himself, his quest for china and a revenge fantasy against various people and groups.
So yeah something utterly unplayable and bizarre with the most cramped collection of gameplay elements, story, narrative and tone ever seen in any piece of interactive media.
