I love the medal system. I like achieving things and this gives us something to do in the game when we don't know what else to do. For me it's going to be really unlikely to earn all the medals because of the one were we have to score 1000 points in a funfest mission and the one where we have to participate in a mission with 30 people. I live in a small country, I don't know anyone nearby who plays pokémon so... yeah. Unless I go to Japan, and even then I have my doubts if I would find 30 people to play a funfest mission with.
I'm almost at 200 medals
