What would alternate in Minecraft if everything was more realistic? Each person who responds will get to add one point. I will start off with an interesting one: If you fall for more than 50 blocks, you automatically die at that point. You cannot see the bottom and your body will be so scared that the heart just stops, knowing it is going to die. Even if there is water, you are already landing with so much magnitude that the resistance will not match, taking damage due to immense force. You will also fall so deep that there is not enough oxygen in your body left to rise back up.
