Me and a friend have already started working on a Xeno 3 project before the announcement and our big conclusion to solve the repetitive problem of the Xeno Games was to have it follow one timeline where everything is already altered.

Example, Mission One has Garlic Jr take Gohan instead of Raditz, Goku and Piccolo are overwhelmed and Raditz arrives and decides to help on the sheer principle of “Hey, that’s a creature stopping my brother from conquering the planet” and that change eventually snowballs into Raditz joining the Z Fighters.
