"Do You Catch Every Pokémon as You go or Wait Until the Endgame?"

I'm about to play Ultra Moon and this is going to be my first Pokémon game since Diamond/Pearl came out and I'm curious to see what the consensus is on this.I'm not sure whether catching every single Pokémon as I go would take too much time and make the game feel like a chore or whether it simply extends the enjoyment of playing the game.What do you usually do? via /r/pokemon http://ift.tt/2EitOVM
