[Question] Do you keep on playing after reaching 200 dwellers?

It's taken a while, but my vault is full. All my questors have Vengeances, the top level dwellers have Dragon's Maws, and most others have armour piercing BOS rifles. There are lots of food, water and energy.

I know many gamers have done this a long time before me so there isn't anything special about this. I'm just asking myself if there is a reason to keep playing, or I should remove the app from my phone. For anyone who filled their vault and kept going, what was your motivation? I'm genuinely curious.
