My complaint:
In 2016 Nintendo shut down the old wifi services which allowed you to trade and get mystery gifts in Pokémon games both of which are required to complete the Pokédex and completely beat the game. None of the older systems work and none of the mii platforms work. My 2DS is basically useless, it feels unfair that just because I can’t afford a new switch or the new games I shouldn’t get the full experience
Suggested solution:
Turn back on the wifi and wireless trade systems
