I am not sure if the hardcore fans will change their minds about Mario 64 being the best but if Mario Odyssey is good enough, they might. It just depends if Mario Odyssey lives up to its hype, I guess. I think it will due to how much effort Nintendo put into it but we have to wait those two months before we know. But in the meantime, we're one week away from that Mario x Rabbids game from being released. That one has been through a lot ever since it was first revealed.
