I wasn't expecting much. Just things that I can do.
Catch UBs
Get Type Null from Gladion at Aether Base
Collect Zygarde cells
Get Cosmog from the alternate dimension
Whatever else you want to do, like work up Battle Royal ranks, Battle Tree, complete the dex, shiny hunt, battle online etc.
Get all 100 TMs
Catch the UB but save Necrozma for when USM comes so you can make a competitive build for two of them.
Also get into balltism.

UB quest definitely takes more than fifteen minutes.
Not that that's a good thing.
