Like the title states, this is a really dumb question that should be answered quickly.
I've beaten the game with 2 different teams and I want to get onto the Side Quests and the Iron Giant, but I'm not exactally sure how to open the side quests.
Do I just keep sending letters to the designated NPC? Or do I have to spam other People over Wi-Fi? And furthermore, is sending letters the only thing that you can do over Wi-Fi?
