Would be cool if they could implement the squid kids into the new Smash game before their actual debut sorta like how they handled the Fire Emblem crew before their western debut. It would be so cool but kinda awkward because we haven't familiarized ourselves with their characters and personalities yet.
I was quite worried about this game and its sales... (new IP from Nintendo. Those usually don't sell very well) But wow, this game...is such a breath of fresh air! Not only that, I haven't seen a single person complain about it. Wow.
