Are you planning anything special for your playthrough of USM? (Egglocke, Non-starter as starter, etc.
Mmmm... Not particularly. Was considering using one of the Hat Pikas, or my shiny Type:Null I SR'd in Moon, but may not. I'll choose a different starter, for definite (so, either Rowlet or Popplio, not decided yet), and will try to use Pokemon that I haven't used for a playthrough yet (though, this may be tough, as there's a fair amount I really like...)
Anyway
Get ready to get those new games hooked up to the Global Link, once you start playing! For people who link them before January, they're handing out Master Balls (one per Ultra version linked), and there's a return of the Global Missions, starting with one that is live in standard Sun/Moon now - and that is to catch 10,000,000 Pokemon before the 28th! This might also apply to the Ultras when they release, but I'm not sure, as it's not been announced whether or not they'll be included, but I'd think so? Anyway, reward is Festival Coins, from 1,000 to 4,000, depending on whether the goal is met and if your game is linked to Global Link.
