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.
Fire Emblem community sadly has too many sjws but imo Fire Emblem Three Houses was still a good game.
Advance Wars is definitely a great series, something about the art in the Advance Wars remake looks a little off to me.
