This was obviously the best E3 conference of 2021 and it was meh at best.
I wanted a new Fire Emblem game and a good Pokemon game but I guess those won't be happening this year.
I already have it on 3DS anyway but I think the display is failing. It dims a bit randomly but eh it could last another decade for all I know.
