After Vegeta sacrifices himself Goku engages Majin Buu, this lightly touches on the Buu saga with some alternative routes/scenes. Then immediately follows on to the Battle of Gods in a world without Vegeta and thus a timeline where SSG is unachieveable, at least without the knowledge of future Saiyans unveiled in DBS.
Tried to make this more cinematic and story based than challenging. As there is passive method to beating Buu quickly (HINT - talk to Majin Buu), using Goku's Ult when he unlocks his final stage deals huge damage to Beerus and defeating Beerus in base form gives you a different victory scene (which is the only real challenge, but it's more there if you really want to prove yourself), but that's not the intended one as there will be a "canon" ending which leads onto my next episode I have in the works.
